Subject: [PATCH] feat(web/ui): consolidate dialogs, cards, and breakpoints
 (Pass 3)

- Unify modal/dialog system; .modal-* are now aliases of .dialog-*
- Migrate WorkspacesPage, start-tool-modal, merge-dialog, workspace-tools-panel to .dialog-*
- Add .card-sm/.card-md/.card-lg/.card-elevated/.card-borderless modifiers
- Apply card utilities across workspaces, projects, ssh-keys, workspace-detail, git-history
- Remove duplicated card-like background/border/padding from page CSS
- Remove 860px breakpoint; standardize on 767px/768px mobile split
- Add docs/development/ui-review-checklist.md
- Archive web-ui-spacing-typography-rework OpenSpec change

+# OpenSpec Spec: Web UI Consolidation & Polish — Modals, Cards, Breakpoints
+
+## Change
+`web-ui-spacing-typography-rework` — Pass 3: Consolidation & Polish
+
+## Parent Proposal
+`openspec/proposals/web-ui-spacing-typography-rework.md`
+
+## Parent Specs
+- `openspec/specs/web-ui-spacing-typography-rework.md`
+- `openspec/specs/web-ui-spacing-typography-rework-pass2.md`
+
+## Status
+spec
+
+---
+
+## 1. Scope of This Spec
+
+This spec covers **Pass 3 (Consolidation & Polish)** only:
+
+- Unify the two modal/dialog systems (`.modal-*` and `.dialog-*`).
+- Consolidate duplicated card patterns across page CSS files into `global.css` modifiers.
+- Standardize responsive breakpoints to the existing token scale (`--bp-sm`, `--bp-md`, `--bp-lg`, `--bp-xl`).
+- Add design-system documentation to `tokens.css`.
+- Add a lightweight code-review checklist to prevent new inline `style={{...}}` layout declarations and undefined class names.
+
+Out of scope for Pass 3:
+- Token additions (Pass 1, done).
+- Inline-style refactor in editor components (Pass 2, done).
+- Behavior changes or new features.
+
+---
+
+## 2. Modal/Dialog Unification
+
+### Current state
+
+Two separate modal implementations exist:
+
+1. `.dialog-overlay` + `.dialog` / `.dialog-lg` (rounded, centered, responsive)
+2. `.modal-overlay` + `.modal-content` (older, square, fixed `min-width: 400px`)
+
+Callers mix both:
+- `.modal-overlay` / `.modal-content`: `WorkspacesPage`, `SessionsPage`, `workspace-tools-panel`, `merge-dialog`, `start-tool-modal`, `start-tool-fab`
+- `.dialog-overlay` / `.dialog`: `instance-list`, `commit-dialog`, `ProjectDialog`, `repository-create-dialog`
+
+### Target state
+
+Deprecate `.modal-*` and make it a backward-compatible alias to `.dialog-*`.
+
+```css
+.modal-overlay {
+  /* alias */
+  composes: dialog-overlay; /* plain CSS fallback: duplicate the rule */
+}
+
+.modal-content {
+  /* alias */
+  composes: dialog; /* plain CSS fallback: duplicate the rule */
+}
+```
+
+Because plain CSS does not support `composes`, the worker must:
+
+1. Keep `.dialog-overlay` and `.dialog` as the canonical implementation.
+2. Make `.modal-overlay` and `.modal-content` duplicate or wrap the same rules.
+3. Migrate callers incrementally:
+   - For components being touched anyway in this pass, replace `.modal-overlay` → `.dialog-overlay` and `.modal-content` → `.dialog`.
+   - For components not being touched, leave the old class names; the aliases keep them working.
+
+### Canonical dialog styles
+
+Ensure `.dialog-overlay` and `.dialog` already in `global.css` cover:
+
+```css
+.dialog-overlay {
+  position: fixed;
+  inset: 0;
+  z-index: 100;
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  padding: var(--space-4);
+  background: rgba(0, 0, 0, 0.45);
+  backdrop-filter: blur(2px);
+}
+
+.dialog {
+  width: 100%;
+  max-width: 32rem;
+  max-height: calc(100vh - var(--space-8));
+  display: flex;
+  flex-direction: column;
+  overflow: hidden;
+  background: var(--panel);
+  border: 1px solid var(--border);
+  border-radius: var(--radius-lg);
+  box-shadow: var(--shadow-xl);
+}
+
+.dialog-lg {
+  max-width: 48rem;
+}
+
+.dialog-header {
+  display: flex;
+  align-items: center;
+  justify-content: space-between;
+  gap: var(--space-3);
+  padding: var(--space-4);
+  border-bottom: 1px solid var(--border);
+}
+
+.dialog-header h2,
+.dialog-header h3 {
+  margin: 0;
+  font-size: var(--font-size-lg);
+  line-height: var(--line-height-tight);
+}
+
+.dialog-body {
+  flex: 1;
+  overflow: auto;
+  padding: var(--space-4);
+}
+
+.dialog-footer,
+.dialog-actions {
+  display: flex;
+  align-items: center;
+  justify-content: flex-end;
+  gap: var(--space-3);
+  padding: var(--space-4);
+  border-top: 1px solid var(--border);
+}
+
+.dialog-close {
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  width: var(--touch-target);
+  height: var(--touch-target);
+  padding: 0;
+  background: transparent;
+  border: none;
+  border-radius: var(--radius-md);
+  color: var(--muted);
+  cursor: pointer;
+}
+
+.dialog-close:hover {
+  background: var(--bg);
+  color: var(--ink);
+}
+```
+
+### Mobile dialog behavior
+
+On viewports narrower than `--bp-md`:
+
+```css
+@media (max-width: 767px) {
+  .dialog-overlay {
+    align-items: flex-end;
+    padding: 0;
+  }
+
+  .dialog {
+    max-width: 100%;
+    max-height: calc(100vh - var(--space-6));
+    border-radius: var(--radius-lg) var(--radius-lg) 0 0;
+  }
+}
+```
+
+Note: this breakpoint will be standardized to `--bp-md` in §4.
+
+---
+
+## 3. Card Consolidation
+
+### Current state
+
+Each page CSS file redeclares card-like containers:
+
+- `.repo-block`, `.workspace-chip`, `.instance-card`, `.settings-section`, `.project-card`, `.session-card`, `.config-profile-card`, etc.
+- Common pattern: `background: var(--panel); border: 1px solid var(--border); border-radius: 10/12/14px;`.
+
+### Target state
+
+Consolidate into `global.css` card modifiers:
+
+```css
+.card {
+  background: var(--panel);
+  border: 1px solid var(--border);
+  border-radius: var(--radius-md);
+}
+
+.card-sm {
+  padding: var(--space-3);
+}
+
+.card-md {
+  padding: var(--space-4);
+}
+
+.card-lg {
+  padding: var(--space-5);
+}
+
+.card-elevated {
+  box-shadow: var(--shadow-sm);
+}
+
+.card-borderless {
+  border-color: transparent;
+}
+```
+
+Then update page CSS files to:
+
+1. Use `.card` / `.card-md` / `.card-lg` where the structure is generic.
+2. Keep only page-specific layout (e.g. `.history-container` two-column grid, `.sessions-grid` column config).
+3. Remove duplicate background/border/border-radius/padding declarations.
+
+### Migration order
+
+Start with the page files that have the most duplication:
+
+1. `styles/pages/workspaces.css`
+2. `styles/pages/sessions.css`
+3. `styles/pages/ssh-keys.css`
+4. `styles/pages/workspace-detail.css`
+5. `styles/pages/projects.css` (if it has card-like patterns)
+6. `styles/pages/git-history.css`
+
+Leave `styles/pages/sessions.css` option-menu styles untouched; they are component-specific, not card patterns.
+
+---
+
+## 4. Breakpoint Standardization
+
+### Current state
+
+Breakpoints are inconsistent:
+
+- `767px` (max-width)
+- `768px` (min-width)
+- `860px` (max-width, one-off in `.shell-body`)
+- `1024px` (min-width)
+
+The token scale already defines:
+
+```css
+--bp-sm: 480px;
+--bp-md: 768px;
+--bp-lg: 1024px;
+--bp-xl: 1280px;
+```
+
+### Target state
+
+1. Remove the `860px` one-off breakpoint.
+2. Standardize all media queries to use `--bp-md` (`768px`) for mobile/desktop split.
+3. Prefer mobile-first `min-width` queries for new/refactored rules.
+4. For existing `max-width: 767px` rules, convert to `max-width: 767px` (equivalent to `--bp-md - 1px`) or refactor to mobile-first `min-width: 768px` where the logic is clearer.
+
+Because CSS custom properties cannot be used directly in `@media` queries, document the pixel values in a comment and use the literal values `480px`, `768px`, `1024px`, `1280px`.
+
+### Specific changes
+
+- `global.css` line 554: remove `@media (max-width: 860px)` and make `.shell-body` collapse at `767px` only.
+- `global.css` line 779: change `max-width: 768px` to `max-width: 767px` for consistency.
+- Page CSS files: update any `767px`/`768px` queries to be consistent with the chosen direction.
+
+### Recommended mobile-first pattern
+
+For refactored rules, prefer:
+
+```css
+.my-component {
+  /* mobile first */
+  padding: var(--space-3);
+}
+
+@media (min-width: 768px) {
+  .my-component {
+    padding: var(--space-4);
+  }
+}
+```
+
+For existing rules that are desktop-first, keep `max-width: 767px` with a comment linking to `--bp-md`.
+
+---
+
+## 5. Token Documentation
+
+Add a documentation block at the top of `apps/web/src/styles/tokens.css`:
+
+```css
+/*
+ * Headquarter Design Tokens
+ *
+ * Naming convention:
+ *   --space-*    : 4px-based spacing scale (1 = 4px, 2 = 8px, ...)
+ *   --font-size-*: fluid type scale from xs to 2xl
+ *   --radius-*   : border radius (sm/md/lg/xl/full)
+ *   --shadow-*   : elevation shadows (sm/md/lg/xl)
+ *   --line-height-*: text line heights
+ *   --bp-*       : responsive breakpoints (use literal px in @media)
+ *
+ * Prefer these tokens over hardcoded px/rem values in all new CSS.
+ */
+```
+
+---
+
+## 6. Code Review Checklist
+
+Add a lightweight markdown file at `docs/development/ui-review-checklist.md`:
+
+```markdown

+- [ ] New radii use `--radius-*` tokens.
+- [ ] New shadows use `--shadow-*` tokens.
+- [ ] No new inline `style={{...}}` blocks for static layout (computed values are OK).
+- [ ] Interactive controls meet `min-height: var(--touch-target)`.
+- [ ] `:focus-visible` states are visible and use `--brand`.

+- [ ] At least two page CSS files have duplicated card rules removed.
+- [ ] The `860px` breakpoint is removed.
+- [ ] All media queries use `480px`, `768px`, `1024px`, or `1280px` consistently.
+- [ ] `tokens.css` has a documentation header.

+
+---
+
+## 8. Verification Plan
+
+1. Run `cd apps/web && npm run typecheck`.
+2. Run `cd apps/web && npm run lint`.
+3. Search for `.modal-overlay` and `.modal-content` in `apps/web/src`; confirm they are aliases or have fewer direct callers.
+4. Search for `860px`; confirm zero matches.
+5. Search for card-like duplicated rules in page CSS; confirm reductions.
+6. Open a dialog on desktop and mobile viewport and verify behavior.
+7. Confirm `tokens.css` has documentation header.
+8. Confirm `docs/development/ui-review-checklist.md` exists.
+
+---
+
+## 9. Next Phase
+
+After this spec is approved, create **tasks** for Pass 3 implementation, then delegate to `sdd-apply`. After Pass 3 is complete, archive the OpenSpec change.

+## Status
+tasks
+
+---
+

+  - `styles/pages/git-history.css`
+
+- [x] 5. Standardize breakpoints
+  - Remove `860px` breakpoint from `global.css`
+  - Make `global.css` line 779 use `767px` instead of `768px`
+  - Ensure all `@media` queries use `480px`, `767px`, `768px`, `1024px`, or `1280px`
+  - Prefer mobile-first `min-width: 768px` for refactored rules
+
+- [x] 6. Add token documentation header to `apps/web/src/styles/tokens.css`
+
+- [x] 7. Create `docs/development/ui-review-checklist.md`
+
+- [x] 8. Verification
+  - Run `cd apps/web && npm run typecheck`
+  - Run `cd apps/web && npm run lint`
+  - Search for `860px` in `apps/web/src`; confirm zero matches
+  - Search for `.modal-overlay` / `.modal-content`; confirm they are aliases or have fewer direct callers
+  - Open a dialog on desktop and mobile viewport and verify behavior
+  - Confirm `tokens.css` documentation header exists
+  - Confirm `docs/development/ui-review-checklist.md` exists
+
+- [x] 9. Update OpenSpec artifacts
+  - Mark tasks in `openspec/tasks/web-ui-spacing-typography-rework-pass3.md` complete
+  - Add final report note
+
+- [x] 10. Archive OpenSpec change
+  - Move `openspec/proposals/`, `openspec/specs/`, `openspec/tasks/` files for this change to `openspec/changes/archive/web-ui-spacing-typography-rework/` (or current archive structure)
+  - Update `progress.md` if applicable
+
+---
+
+## Acceptance Criteria
+
+- All tasks above are completed.
+- `npm run typecheck` passes.
+- `npm run lint` passes.
+- `.modal-overlay` and `.modal-content` are aliases/wrappers of `.dialog-*`.
+- At least two `.modal-*` callers migrated to `.dialog-*`.
+- `.card` family exists and is used by at least two page CSS files.
+- `860px` breakpoint removed.
+- `tokens.css` has documentation header.
+- `docs/development/ui-review-checklist.md` exists.
+- OpenSpec change archived.
+
+---
+
+## Notes
+
+- Keep aliases for backward compatibility; do not delete `.modal-*` classes if other callers remain.
+- Do not change behavior of dialogs; only visual unification.
+- Do not remove page-specific layout grids; only remove duplicated card-like background/border/padding.
+- Prefer one commit per major area (modals, cards, breakpoints, docs).

+Implemented Pass 1 (Foundations) of the web UI spacing/typography/visual-rhythm rework.
+
+**Changed files:**
+- `apps/web/src/styles/tokens.css` — expanded spacing, radius, line-height, shadow, layout, touch-target, sidebar-width, mobile-nav-height tokens; added documentation header.
+- `apps/web/src/styles/global.css` — added primitive classes: `.btn`/`.btn-primary`/`.btn-secondary`/`.btn-sm`/`.btn-icon`/`.btn-danger`, `.link-button`, `.form-input`/`.form-textarea`, `.checkbox-label`/`.checkbox-label-compact`, `.hint`, `.form-error`/`.error-message`, `.alert`/`.alert-error`/`.alert-warning`/`.alert-info`, `.loading-state`, `.badge`/`.badge-success`/`.badge-secondary`, `.text-muted`, `.profile-avatar-section`/`.avatar-*`, `.mobile-detail-back`, `.button-secondary` alias; added `:focus-visible` rings for `.nav-item`, `.mobile-nav-item`, `.tab`, `.tree-entry`, `.btn`, `.form-input`, `.form-textarea`, `.link-button`.
+- `apps/web/src/styles/utilities.css` — added `.mobile-detail-*` view classes, `.mobile-list-search`/`.mobile-list-search-input`, SSH key `.key-signing`/`.key-verification`/`.signature-result`/`.verify-result`, profile mobile avatar classes, replaced hard-coded `64px` and `44px` values with `--mobile-nav-height`/`--touch-target`, and removed a redundant `.mobile-nav-item` override.
+- `apps/web/src/components/features/config-profiles/ConfigProfileListSidebar.tsx` — replaced inline `0.7rem` styles with `.badge`/`.badge-secondary`; added `.delete-btn`.
+- `apps/web/src/components/features/config-profiles/ConfigProfileEditorPanel.tsx` — switched Discard button to `.button-secondary` alias.
+- `apps/web/src/components/features/tool/instance-list.tsx` — replaced inline checkbox styles with `.checkbox-label-compact`.
+- OpenSpec artifacts: `openspec/proposals/web-ui-spacing-typography-rework.md`, `openspec/specs/web-ui-spacing-typography-rework.md`, `openspec/tasks/web-ui-spacing-typography-rework.md` (tasks marked done).
+- `ui-audit-spacing-typography.md` audit report.
+
+**Commits (on `feat/web-ui-foundations`, merged into `dev`):**
+1. `feat(web/ui): expand design tokens and add primitive component styles`
+2. `feat(web/ui): add mobile detail/search, ssh/profile utilities and nav-height tokens`
+3. `feat(web/ui): replace inline font-size violations and use new primitives in components`
+4. `docs(openspec): add web ui spacing/typography proposal, spec, tasks and audit`
+5. `docs(openspec): mark pass 1 tasks complete`
+
+**Validation:**
+- `npm run typecheck` passes.
+- `npm run lint` passes.
+- `npm run build` passes (only pre-existing chunk-size warnings).
+- Class coverage check: 486 classes referenced across `src/`; only false-positive `page` lacks a rule. All audit-listed missing classes now have rules.
+- Spot-checked mobile detail view, SSH key signing/verification, profile avatar classes, and mobile nav/FAB height token usage — all present.
+
+**Open risk/question:**
+- Push to `origin dev` is blocked by the runtime safety policy because the required override disables SSH host-key checking (`StrictHostKeyChecking=no`). The merge is complete locally and `dev` is ready.
+
+**Recommended next step:**
+- Run the push from the parent session or approve the blocked command:
+  ```bash
+  cd /home/user/headquarter && GIT_SSH_COMMAND='ssh -i ~/.ssh/id_ed25519_headquarter -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes' git push origin dev
+  ```
+- After push, proceed to Pass 2 (Component Cleanup) or handle other requests.
