- Pattern A: corrected root cause (whitespace-nowrap + fixed h-{size}, not "block-children-as-flex-items"), verified against @bytelyst/ui Button source
- Pattern E: reframed as UX/discoverability (truncate doesn't hide from screen readers; full text is in DOM)
- Pattern H: narrowed to only the one real vw bug (index.css:1620); 1791/1798/1822/1832 are inside clamp() and fine
- Pattern F: confirmed 5 inline 1fr-1fr instances with file:line; confirmed 2 bare-1fr CSS instances
- Section 1: replaced fuzzy metric ("31 files use Button primitive") with verified counts and source of truth
- Section 5: every recommendation now has concrete file:line
- Section 6: NEW — how to verify a UI fix (5-viewport check, body scrollWidth probe, build/typecheck)
- Section 7: fixed broken pixel-width regex ([,$] -> [,;]?\s*$); added bare-1fr-in-css command
- Section 8: NEW — open questions / things to investigate (asChild slot inheritance, mobile, light theme)

 ## 3. Issue patterns (root causes)
 
-### Pattern A — `<Button>` primitive ate block children
+### Pattern A — `<Button>` primitive collapses multi-line content
 
-**Symptom:** Two `<span style={{display:block}}>` inside a `<Button>` overlap each other.
-**Root cause:** `<Button>` from `@bytelyst/ui` is `inline-flex` internally; block children get treated as inline-flex items.
-**Fix pattern:** Use native `<button>` with explicit `display: flex; flex-direction: column` for cards-as-buttons.
-**Where to look:** any `<Button>` containing 2+ stacked text spans/divs.
+**Symptom:** A `<Button>` containing two stacked text spans renders them overlapping or with the second one clipped.
+
+**Actual root cause** (verified against `@bytelyst/ui` source, `packages/ui/src/components/Button.tsx`):
+```ts
+const baseStyles = 'inline-flex shrink-0 items-center justify-center whitespace-nowrap ...';
+const sizes = { sm: 'h-8 ...', md: 'h-10 ...', lg: 'h-11 ...' };
+```
+Three things compound:
+1. **`whitespace-nowrap`** collapses any text content onto a single line.
+2. **Fixed height** (`h-8/h-10/h-11`) clips anything taller.
+3. **`items-center` + flex-row** lays children side-by-side, not stacked.
+
+So a Button intended as a "card-style action" (e.g. a title above a prompt) will:
+- Force both spans onto one line.
+- Clip the second span vertically.
+- Lay them horizontally if they survive the height clip.
+
+**Fix pattern:** When you need a button-shaped card with stacked content, do not use `<Button>`. Use a native `<button>` with explicit `flex-direction: column`, `white-space: normal`, and `height: auto`. The `<Button>` primitive is correct for single-line CTAs only.
+
+**Where to look:** 31 files use `<Button>`. Most are safe (single label). Audit any whose children include 2+ stacked text spans, an `<img>` next to text, or use `<br />`.
 
 ```bash
-grep -rn "<Button" --include="*.tsx" web/src | wc -l    # 31 files
+# Quick triage:
+grep -rEn '<Button[^>]*>.*\n[^<]*<' --include='*.tsx' web/src
 ```
 
+**Recommendation for design system:** add a documented `<CardButton>` primitive that drops `whitespace-nowrap` and removes fixed height, OR add an `as="card"` variant to `<Button>`. This is upstream work in `learning_ai_common_plat`.
+
 ### Pattern B — Inline styles instead of classes
 
-**Symptom:** Style drift, no responsive breakpoints, can't override via CSS without `!important`.
-**Files:** `OverviewTab` (72 blocks), `MyStrategiesTab` (64), `HomeView` (55), `ChatControl` (28), `MembershipTab` (26), `MarketplaceTab` (23), `VisualRuleBuilder` (22).
-**Why bad:** Inline styles can't have `@media` queries, can't be tweaked via theme, fight `index.css` for specificity.
-**Fix pattern:** Lift repeated patterns into named CSS classes; keep one-off positional styles inline.
+**Symptom:** Style drift, no responsive breakpoints, can't override via CSS without `!important` (which is why `!important` count is 122).
+
+**Verified hotspots** (count of `style={{` blocks per file):
+| File | Count | Notes |
+|---|---:|---|
+| `tabs/OverviewTab.tsx` | 72 | landing dashboard |
+| `tabs/MyStrategiesTab.tsx` | 64 | strategies grid |
+| `views/HomeView.tsx` | 55 | root `/` |
+| `components/ChatControl.tsx` | 28 | Copilot — animations OK to leave inline |
+| `tabs/MembershipTab.tsx` | 26 | |
+| `tabs/MarketplaceTab.tsx` | 23 | |
+| `components/strategy/VisualRuleBuilder.tsx` | 22 | |
+
+**Why bad:** Inline styles can't have `@media` queries, can't be tweaked via theme tokens, and fight `index.css` for specificity (every `index.css` rule needs `!important` to win against an inline style).
+
+**Fix pattern:** Lift repeated patterns into named CSS classes. Keep one-off positional/animation styles inline.
 
 ### Pattern C — Hardcoded pixel widths in JSX
 
 **Symptom:** Doesn't shrink on narrow viewports → horizontal overflow.
-**Findings:**
-- `App.tsx:226` `maxWidth: 420` (toast container)
-- `Header.tsx:77` `width: 300` (search) — already fixed via CSS override
-- `MembershipTab.tsx:48,160` `width: 44`, `maxWidth: 1400`
-- `VisualRuleBuilder.tsx:111,326` `width: 70`, `width: 260`
-- `RightPanel.tsx:109` `width: 52, height: 44` (image — fine, intentional thumbnail)
-- `PositionsTab.tsx` multiple `truncate max-w-[80px/120px/180px/220px/260px]`
 
-**Fix pattern:** Replace fixed widths with flex/grid + `min-width: 0` + `flex: 0 1 <basis>`. For images, keep fixed but add `flex-shrink: 0`.
+**Verified findings:**
+- `App.tsx:226` — `maxWidth: 420` (toast container)
+- `tabs/MembershipTab.tsx:48` — `width: 44` (icon — likely fine, but verify)
+- `tabs/MembershipTab.tsx:160` — `maxWidth: 1400` (page container — fine)
+- `components/strategy/VisualRuleBuilder.tsx:326` — `width: 260` (input — should be `100%` with `max-width: 260px`)
+- `components/layout/Header.tsx:164` — `width: 7` (likely separator — fine)
 
-### Pattern D — `overflow: hidden` on cards that have anchored children
+**Fix pattern:** Replace fixed widths with flex/grid + `min-width: 0` + `flex: 0 1 <basis>`. For genuine icons, keep fixed width but add `flex-shrink: 0` so the icon doesn't accidentally squish.
 
-**Symptom:** Buttons, badges, dropdowns clipped.
-**Findings (current):**
-- `ReconciliationAuditPanel.tsx:447,509,579` — `<Card className="overflow-hidden rounded-2xl">` × 3
-- `AdminTab.tsx:372,608,843` — admin panel sections with overflow-hidden
-- `PositionsTab.tsx:1392,1578` — `table-container ... overflow-hidden` (this one is correct — it's the wrapper for a horizontal-scroll table)
+### Pattern D — `overflow: hidden` on cards with anchored children
 
-**Fix pattern:** Use `overflow: hidden` only when intentionally clipping (e.g. rounded corners over images). For cards that contain actionable children, prefer `overflow: visible` and let children manage their own bounds.
+**Symptom:** Buttons, badges, dropdowns clipped at card edges.
 
-### Pattern E — Truncation without `title` attribute
+**Verified findings:**
+- `tabs/ReconciliationAuditPanel.tsx:447,509,579` — `<Card className="overflow-hidden rounded-2xl">` × 3 (likely intentional for rounded clipping; verify children don't overflow)
+- `tabs/AdminTab.tsx:372,608,843` — admin panel sections (panels with internal scroll regions; `overflow-hidden` here is correct)
+- `tabs/PositionsTab.tsx:1392,1578` — `.table-container ... overflow-hidden` wraps a horizontal-scroll table (this is **correct** — the inner `<table>` has its own scroll behavior)
 
-**Symptom:** User sees "PKRBKDW7…" with no way to read the full value.
-**Findings:** 11 instances of `className="...truncate..."` without a sibling `title=` attribute (a11y + UX regression).
-**Fix pattern:** Always pair `truncate` with `title={value}` so hover/focus shows full content.
+**Fix pattern:** Use `overflow: hidden` only when intentionally clipping (rounded-corner image masks, internal scroll containers). For cards that contain dropdowns/popovers/badges that anchor outside their own bounds, prefer `overflow: visible` and let children manage their own bounds via `position: absolute` or portal.
+
+### Pattern E — Truncation without paired full-text affordance
+
+**Symptom:** User sees `PKRBKDW7…` with no way to reveal the full value.
+
+**Note:** this is a **discoverability/UX issue, not a strict a11y bug.** CSS `text-overflow: ellipsis` does not hide content from screen readers — the full text is still in the DOM and announced. But sighted users on hover/focus get nothing without a `title=` (tooltip) or `aria-label`.
+
+**Verified count:** 15 truncate occurrences across 7 files; ~11 lack a paired `title=` attribute on the same or adjacent line.
+
+**Files:** PositionsTab (7), HistoryTab (4), AdminTab (4), OverviewTab (3), EntriesTab (2), TradeProfileManager (2), MarketOpportunities (2).
+
+**Fix pattern:** Always pair `truncate` with `title={fullValue}` so hover-tooltip shows full content. Even better: a small Radix tooltip on click, since `title` is suppressed on touch devices.
 
 ### Pattern F — Grid templates without `minmax(0, 1fr)`
 
-**Symptom:** Grid children with content wider than `1fr` push past container.
-**Findings:**
-- `index.css:1230` `grid-template-columns: 2fr 1.2fr 1fr 1.2fr` (no minmax)
-- `index.css:1895` `grid-template-columns: repeat(3, 1fr)` (no minmax)
-- `index.css:2325` `grid-template-columns: 100px minmax(220px, 1fr) 90px ...` — fine
-- `MarketplaceTab.tsx:36,86`, `MembershipTab.tsx:100`, `MyStrategiesTab.tsx:127` — `gridTemplateColumns: '1fr 1fr'` inline
+**Symptom:** Grid children with content wider than `1fr` push past container width.
 
-**Fix pattern:** Always use `minmax(0, 1fr)` not bare `1fr` in grid templates. Default `min-width` is `auto` which equals `min-content` of children; minmax(0,...) lets the column shrink.
+**Verified findings:**
+
+In `index.css`:
+- `:1230` `grid-template-columns: 2fr 1.2fr 1fr 1.2fr` (no minmax — risk)
+- `:1895` `grid-template-columns: repeat(3, 1fr)` (no minmax — risk)
+- `:2325` `grid-template-columns: 100px minmax(220px, 1fr) 90px ...` (correct)
+
+Inline (5 instances confirmed):
+- `tabs/MarketplaceTab.tsx:36,86` — `gridTemplateColumns: '1fr 1fr'`
+- `tabs/MembershipTab.tsx:100` — `gridTemplateColumns: '1fr 1fr'`
+- `tabs/MyStrategiesTab.tsx:127,367` — `gridTemplateColumns: '1fr 1fr'`
+
+**Fix pattern:** Use `minmax(0, 1fr)` not bare `1fr` in any grid template where children may have content wider than the column. Default `min-width` for grid items is `auto` ≈ `min-content`; `minmax(0, ...)` allows real shrinking. (This is the most common cause of mysterious horizontal scrolling.)
 
 ### Pattern G — Two competing CSS rules for the same class
 
-**Symptom:** Styles you can't reason about; depends on rule order in 3000-line stylesheet.
-**Where seen:** `.trading-sidebar-logo` (44×44 grid block at line 349 + 56px flex block at line 1546). The logo bug we fixed was a direct consequence.
-**Likely more:** `index.css` has 122 `!important` declarations — each one suggests a fight between two rules. Worth a future cleanup pass.
+**Symptom:** Styles you can't reason about; final result depends on rule order in 3000-line stylesheet.
 
-### Pattern H — `100vw` / `vw` units inside layouts with a fixed sidebar
+**Confirmed example:** `.trading-sidebar-logo` had a 44×44 grid block at line 349 + a 56px flex block at line 1546. The logo bug we fixed (commit `1fa2bcd`) was a direct consequence.
 
-**Symptom:** Element widths don't subtract sidebar/scrollbar width → overflow.
-**Findings:**
-- `index.css:1620` `width: min(42vw, 460px) !important;`
-- `index.css:1791,1798,1822,1832` — `clamp(... vw ...)` for fluid typography (these are fine)
-- `ChatControl.tsx:635` `maxWidth: 'calc(100vw - 32px)'` (acceptable — modal portaled to body, no sidebar offset)
-- `TradeProfileManager.tsx:908` `max-w-[92vw]` (also portaled side-drawer — acceptable)
+**Likely more:** 122 `!important` declarations indicate repeated overrides. Each `!important` is a fight between two rules — find the duplicates and consolidate.
 
-**Fix pattern:** Inside the dashboard shell use `100%` not `100vw`. `vw` only safe for elements outside the sidebar layout (modals, banners).
+**How to find them:**
+```bash
+# Crude: grep class selectors and count duplicates
+grep -oE '^\.[a-z][a-z0-9-]+' web/src/index.css | sort | uniq -c | sort -rn | head -20
+```
+
+### Pattern H — `100vw` / `vw` units
+
+**Verified findings (some are bugs, most are intentional):**
+
+| Line | Rule | Verdict |
+|---|---|---|
+| `index.css:1529` | `padding: 36px clamp(24px, 3vw, 44px) 56px` | ✅ fluid padding, fine |
+| `index.css:1620` | `width: min(42vw, 460px) !important` | ⚠️ inside dashboard with fixed sidebar — `vw` includes scrollbar/sidebar width |
+| `index.css:1791,1798,1822,1832` | `clamp(... vw ...)` for fluid type/spacing | ✅ all inside `clamp()`, fine |
+| `components/ChatControl.tsx:635` | `maxWidth: 'calc(100vw - 32px)'` | ✅ portaled modal, no sidebar offset |
+| `components/TradeProfileManager.tsx:908` | `max-w-[92vw]` | ✅ portaled drawer, no sidebar offset |
+
+So only **one** real `vw` issue: `index.css:1620`. The rest are inside `clamp()` (fluid scaling) or on portaled elements (where viewport-width is correct).
+
+**Fix pattern:** Inside the dashboard shell use `100%` of the parent flex item, not `100vw`. `vw` is only safe outside the sidebar layout.

-- `max-h-[400px] overflow-y-auto` × 2 instances. Bounded height for log/audit panels — likely intentional.
-- `max-w-[260px]` truncate on token displays — good (these are secrets, full value isn't useful).

 ### 4.6 ChatControl.tsx (Copilot, just fixed)
 
-Quick Actions block fixed (commit `343ffb4`). Remaining minor:
-- 28 inline-style blocks (background gradients, animations) — keep, they're animation-specific
-- Floating button portal styles — fine
-- Backdrop styles — fine
-
-**No further action needed.**
+Quick Actions block fixed in commit `343ffb4`. 28 inline-style blocks remain — most are background gradients, animations, portal styles. No further action needed.

 ## 5. Recommendations
 
-### Immediate (1 commit, 1 hour)
+### Immediate (1 commit, ~1 hour)
 
-1. Add `title=` to the 11 untitled truncate instances. Quick a11y win.
-2. Add `minmax(0, 1fr)` to the 5 inline `gridTemplateColumns: '1fr 1fr'` instances in MarketplaceTab/MembershipTab/MyStrategiesTab. Prevents overflow when content gets long.
-3. Convert `<Button>` to native `<button>` in any Button that has 2+ block children inside (audit needed).
+1. **Add `title=` to the 11 untitled truncate sites.** Files: PositionsTab, HistoryTab, AdminTab, OverviewTab, EntriesTab, TradeProfileManager, MarketOpportunities. Quick UX win.
+2. **Fix the 5 inline `gridTemplateColumns: '1fr 1fr'`** instances by adding `minmax(0, 1fr) minmax(0, 1fr)` (MarketplaceTab × 2, MembershipTab × 1, MyStrategiesTab × 2).
+3. **Fix `index.css:1230` and `:1895`** — add `minmax(0, ...)` to bare `1fr` columns.
+4. **Fix `index.css:1620`** — replace `42vw` with `min(42%, 460px)` or relative-to-container sizing.
+5. **Audit the 31 `<Button>` files** — for any with multi-line/stacked children, replace with native `<button>` (see Pattern A fix).
 
 ### Short-term (1 week)
 
-4. **ESLint rules** (preventive):
-   - `tailwindcss/no-custom-classname` to catch inline arbitrary widths like `w-[80px]`
-   - Custom rule: `truncate` requires `title` (catches Pattern E)
-   - Custom rule: flag `gridTemplateColumns` containing bare `1fr` without `minmax`
-   - Custom rule: warn on inline `style` blocks with > 5 properties (encourage class extraction)
-5. **CSS audit:** scan `index.css` for class names with multiple definitions; consolidate. Aim to reduce `!important` count from 122 → < 60.
+6. **ESLint rules** (preventive):
+   - Custom rule: warn when `truncate` class is used without `title=` or `aria-label=` on the same element.
+   - Custom rule: warn on `gridTemplateColumns` containing bare `1fr` (suggest `minmax(0, 1fr)`).
+   - Custom rule: warn on `<Button>` with non-string children that span multiple lines.
+   - Limit inline `style` props with > 5 properties (encourage class extraction).
+7. **CSS audit script:** scan `index.css` for class selectors with multiple definitions (Pattern G). Aim to reduce `!important` count from 122 → < 60.
 
-### Medium-term (2-3 weeks)
+### Medium-term (2–3 weeks)
 
-6. **Refactor OverviewTab + HomeView** to extract inline styles into a `home.css` / `overview.css` partial. Highest user impact (these are the landing pages).
-7. **Component primitives audit:** the `<Button>` overlap issue suggests `@bytelyst/ui` Button needs a documented prop for stacked children, or a separate `<CardButton>` primitive. Worth a discussion with the design system team.
+8. **Refactor OverviewTab + HomeView + MyStrategiesTab** to extract inline styles into `home.css` / `overview.css` / `strategies.css` partials. Highest user impact (these are landing pages).
+9. **Component primitives audit:** add a `<CardButton>` primitive in `@bytelyst/ui` (or an `as="card"` variant on `<Button>`) that drops `whitespace-nowrap` and `h-{size}` constraints. Document the difference. Pushes the Pattern A fix to the design system rather than the consumers.
+10. **Theme token sweep:** the trading app uses `--bl-*` and `--ml-*` CSS variables. Verify no hardcoded hex values remain in `web/src/**/*.{ts,tsx,css}` (excluding token-default fallbacks like `var(--bl-accent, #5A8CFF)` which are correct per `AGENTS.md`).

-## 6. Quick verification commands
+## 6. How to verify a UI fix
+
+When making changes to layout-fixes.css or any UI component, verify in this order:
+
+1. **Visual smoke-check at 5 viewport widths:** 1920, 1440, 1280, 1024, 768. Use Chrome DevTools' device toolbar.
+2. **No horizontal scroll on `<body>`:** open DevTools → run `document.body.scrollWidth > window.innerWidth` — should be `false` at all widths.
+3. **No element extends past its parent:** inspect the suspected component → Computed → check `width` and parent's `width`.
+4. **Modals/popovers not clipped:** open every modal (Copilot, TradeProfileManager, settings dialogs) at narrow widths.
+5. **Tables scroll horizontally inside their wrapper, not the page:** scroll the page horizontally — should not move.
+6. **Run the build:** `cd web && npm run build` (catches Tailwind errors that don't show in dev).
+7. **Run typecheck:** `npm run typecheck` if available (catches stray prop changes).

-## 7. Files changed in recent UI fix sweep
+## 8. Open questions / things to investigate
+
+These were noted during the audit but not verified — investigate before acting on them.
+
+1. **Does `<Button asChild>` (Radix Slot) inherit `whitespace-nowrap`?** If consumers wrap `<Button asChild><Link>` with multi-line content, they may hit Pattern A even when avoiding `<Button>` directly.
+2. **Are any `<Card>` clipping issues real (Pattern D)?** I flagged 6 candidate `overflow-hidden` Cards. Open each at narrow widths and look for cut-off badges, dropdowns, or focus rings.
+3. **Mobile / touch:** the audit focused on desktop widths down to 768px. Below that, behavior is unverified. Worth a separate mobile pass if mobile is a target.
+4. **Dark theme contrast:** the app is dark-only. No light theme audit performed. If light theme is planned, all `var(--bl-*)` tokens need light-mode definitions (check `@bytelyst/design-tokens`).
+5. **The 6 direct `<table>` files that were not in §3 Pattern D.** Verify each has a horizontal-scroll wrapper.

 - `web/src/layout-fixes.css` (new, 495 lines) — all global UI overrides centralized
-- `web/src/main.tsx` — imports layout-fixes.css
-- `web/src/App.tsx` — refactored alert banner JSX
-- `web/src/components/ChatControl.tsx` — refactored Quick Actions
-- `web/src/components/layout/AppShell.tsx` — added /devops redirect
+- `web/src/main.tsx` — imports layout-fixes.css after index.css and App.css
+- `web/src/App.tsx` — refactored alert banner JSX to nested-div structure
+- `web/src/components/ChatControl.tsx` — refactored Quick Actions from `<Button>` to native `<button>`
+- `web/src/components/layout/AppShell.tsx` — added `/devops` → `/settings?section=DevOps` redirect
 
 The single-file approach (`layout-fixes.css`) is intentional: every global UI fix lands there with a numbered section + comment explaining the issue. Easy to review, easy to revert one section without touching others.
