- Add optional globalDir parameter to resolveProject(), getDefaultProject(),
  setDefaultProject(), and clearDefaultProject() for test isolation
- Remove ESLint suppression by using void operator for intentionally unused var

+# Task: KB-059 - Lock Mobile Viewport to Prevent Zoom
+
+**Created:** 2026-03-30
+**Size:** S
+
+## Review Level: 1 (Plan Only)
+
+**Assessment:** Small, focused change to HTML meta tags and CSS. No logic changes, minimal blast radius. Reversible by reverting the viewport meta tag.
+**Score:** 2/8 — Blast radius: 0, Pattern novelty: 0, Security: 0, Reversibility: 2
+
+## Mission
+
+Prevent mobile browsers from zooming in/out on the dashboard to create an app-like experience where the view stays locked at a consistent scale. Update the viewport meta tag and add necessary CSS to disable pinch-to-zoom and double-tap zoom behaviors while maintaining accessibility for form inputs.
+
+## Dependencies
+
+- **None** — This task is independent and can be completed before or alongside KB-035
+
+## Context to Read First
+
+1. `packages/dashboard/app/index.html` — HTML template containing the current viewport meta tag
+2. `packages/dashboard/app/styles.css` — Global styles including mobile responsive `@media` queries
+3. `packages/dashboard/app/App.tsx` — Root component to understand layout structure
+
+## File Scope
+
+- `packages/dashboard/app/index.html` — modify viewport meta tag
+- `packages/dashboard/app/styles.css` — add CSS to prevent zoom gestures (optional, if needed beyond meta tag)
+
+## Steps
+
+### Step 0: Preflight
+
+- [ ] Required files exist at `packages/dashboard/app/index.html` and `packages/dashboard/app/styles.css`
+- [ ] No dependencies blocking this task
+
+### Step 1: Update Viewport Meta Tag
+
+- [ ] Read current `index.html` and locate the viewport meta tag
+- [ ] Update the viewport meta tag to prevent zoom:
+  - Change from: `content="width=device-width, initial-scale=1.0"`
+  - Change to: `content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no, viewport-fit=cover"`
+- [ ] Ensure the meta tag includes `viewport-fit=cover` for proper handling of notches/safe areas on modern mobile devices
+- [ ] Verify the tag remains valid HTML5
+
+**Artifacts:**
+- `packages/dashboard/app/index.html` (modified)
+
+### Step 2: Add Touch-Action CSS (if needed)
+
+- [ ] Check if additional CSS is needed to prevent zoom gestures that bypass the meta tag (iOS Safari sometimes ignores user-scalable)
+- [ ] If needed, add to the `html, body` selector in `styles.css`:
+  - `touch-action: pan-x pan-y;` — allows horizontal/vertical panning but not pinch zoom
+  - `-webkit-touch-callout: none;` — prevents iOS callout menu on long press (optional, assess if it affects UX)
+- [ ] Ensure form inputs still work correctly (inputs should not be blocked from receiving focus)
+
+**Artifacts:**
+- `packages/dashboard/app/styles.css` (modified if needed)
+
+### Step 3: Testing & Verification
+
+> ZERO test failures allowed. Full test suite as quality gate.
+
+- [ ] Create test file `packages/dashboard/app/__tests__/mobile-viewport.test.ts` that validates:
+  - Viewport meta tag exists in index.html
+  - Viewport meta tag contains `maximum-scale=1.0`
+  - Viewport meta tag contains `user-scalable=no`
+  - Viewport meta tag contains `viewport-fit=cover`
+- [ ] Run full test suite: `pnpm test packages/dashboard`
+- [ ] Fix all failures
+- [ ] Build passes: `pnpm build`
+- [ ] Verify no console warnings or errors
+
+**Artifacts:**
+- `packages/dashboard/app/__tests__/mobile-viewport.test.ts` (new)
+
+### Step 4: Documentation & Delivery
+
+- [ ] Check `packages/dashboard/README.md` — add a brief note about mobile app-like experience if a "Mobile Support" section exists
+- [ ] Out-of-scope findings created as new tasks via `task_create` tool
+
+## Documentation Requirements
+
+**Must Update:**
+- None required — the viewport change is self-documenting
+
+**Check If Affected:**
+- `packages/dashboard/README.md` — add mobile behavior note if a mobile section exists
+
+## Completion Criteria
+
+- [ ] All steps complete
+- [ ] Viewport meta tag prevents zoom (`user-scalable=no`, `maximum-scale=1.0`)
+- [ ] `viewport-fit=cover` included for safe area support
+- [ ] All tests passing (including new `mobile-viewport.test.ts`)
+- [ ] Build passes
+- [ ] Mobile browsers cannot zoom the dashboard view (feels like a native app)
+
+## Git Commit Convention
+
+Commits at step boundaries. All commits include the task ID:
+
+- **Step completion:** `feat(KB-059): complete Step N — description`
+- **Bug fixes:** `fix(KB-059): description`
+- **Tests:** `test(KB-059): description`
+
+## Do NOT
+
+- Add JavaScript-based zoom prevention (unnecessary, meta tag is sufficient)
+- Block legitimate accessibility features (screen readers should still work)
+- Prevent input focus or text selection (only prevent zoom)
+- Skip tests or rely on manual verification only
+- Modify desktop viewport behavior
