## Project handoff

### Stack
- Static HTML entry point: `index.html`
- Styling: `style.css`
- Client-side behavior: vanilla JavaScript in `app.js`
- Visual reference: `docs/design-reference.png` (guidance only, not a runtime dependency)

### Existing work
- `app.js` defines dashboard state for total reps, workouts, weekly activity, and a four-exercise routine.
- Summary values, activity bars, and routine rows are rendered from state.
- The rep counter supports increment/decrement controls with bounds from 1 to 99.
- The log action updates total reps, workout count, Saturday activity, matching routine completion, and user feedback.
- Accessibility attributes are added for summary metrics, the chart, controls, and routine completion states.
- The supplied design brief calls for a dark responsive dashboard with lime progress accents, electric-blue actions, rounded cards, strong typography, and a mobile layout.

### Constraints and preservation guidance
- Preserve the existing dashboard information architecture and the intended dark/lime/blue visual system.
- Keep the primary Quick Add Reps flow prominent: choose an exercise, adjust reps, log reps, and immediately update totals, activity, routine completion, and feedback.
- Keep the design responsive by collapsing navigation and dashboard columns on smaller screens.
- Do not treat `docs/design-reference.png` as authoritative or require it at runtime.
- Do not add a framework or backend unless explicitly requested; the current implementation is a static vanilla web app.

### Blockers and verification
- The supplied file listing does not expose the contents of `index.html`, so verify that it contains the expected dashboard element IDs used by `app.js` (`#app`, `#total-reps`, `#workouts`, `#rep-count`, `#chart`, `#routine-list`, `#exercise`, `#minus`, `#plus`, `#log-reps`, and `#feedback`).
- Verify that `index.html` loads `app.js` after or with the appropriate script behavior. The provided JavaScript has a renderer and event handlers, but the supplied handoff does not prove the browser entry point is wired.
- Generated code was not executed; browser behavior, responsive layout, and visual matching remain unverified.
- No logo file was supplied.

## Visual handoff
VISUAL HANDOFF:
- Design reference: `docs/design-reference.png`. It is non-authoritative visual guidance; the user prompt and runnable target remain authoritative.
- Design brief: Create a dark, responsive exercise-tracking dashboard inspired by the supplied reference: near-black surfaces, lime-green progress accents, electric-blue action accents, rounded cards, and strong typographic hierarchy. Use semantic HTML for the dashboard structure, CSS for the responsive two-column layout and visual system, and vanilla JavaScript for live rep logging. The primary interaction is a Quick Add Reps card where users select an exercise, adjust reps, log them, and see dashboard totals, streak/activity, and today’s routine update immediately. Keep the interface usable on mobile by collapsing navigation and dashboard columns without relying on the reference image as a runtime asset.
