SOTA · 装了 skill：final message（t1-audit，第 1 次，Codex）

Audited all four project files. **No files changed.** This is a static code audit: `index.html` does not load `app.js`, so the dropdown click handler currently never runs. Other open states have no handlers. All motion fixes below are in [styles.css](C:/Users/<user>/AppData/Local/Temp/asv-improve-an-9e585535/work/styles.css), ordered by priority. | Priority | Severity | Location | Finding | Exact replacement | |---|---|---|---|---| | 1 | HIGH | Line 8, `.palette` | The documented ~100 daily keyboard openings should respond immediately. | Replace its declaration with `transition: none;` | | 2 | HIGH | Line 1, `.dropdown` | `400ms ease-in` delays the initial response and makes opening sluggish. | `transition: transform 200ms cubic-bezier(0.23, 1, 0.32, 1), opacity 200ms cubic-bezier(0.23, 1, 0.32, 1);` | | 3 | HIGH | Lines 4–5, `.modal` | Scaling from zero over 500ms creates excessive movement. | Use the modal replacement below. | | 4 | HIGH | Line 6, `.accordion` | Animating `height` forces repeated layout over 500ms. | Replace `transition: height 0.5s ease;` with `transition: none;`. Keep both height values. This is the smallest safe fix; a smooth reveal needs additional structure. | | 5 | MEDIUM | Missing reduced-motion rule | Dropdown and modal movement have no preference override. | Append the reduced-motion block below, after the other rules. | | 6 | MEDIUM | Line 3, `.btn` | `transition: all` can animate unintended properties. No button state currently changes a visual property. | Replace with `.btn { transition: none; }` | | 7 | MEDIUM | Line 9, `.popover` | Center scaling contradicts its documented connection to the top-bar trigger. | Replace `transform-origin: center;` with `transform-origin: top left;` **if positioned below and left-aligned with the trigger**. Placement is absent from this prototype; use `top right` for right alignment or `top center` for centered alignment. | | 8 | LOW | Lines 10–11, `.card` | A 700ms linear shadow transition makes routine hover feedback linger; hover is also ungated on touch devices. | Use the card replacement below. | Replace lines 4–5 with: ```css .modal { opacity: 0; transform: scale(0.96); transition: transform 250ms cubic-bezier(0.23, 1, 0.32, 1), opacity 250ms cubic-bezier(0.23, 1, 0.32, 1); } .modal.open { opacity: 1; transform: scale(1); } ``` Keep the modal’s centered transform origin; it is appropriate here. Replace lines 10–11 with: ```css .card { transition: none; } @media (hover: hover) and (pointer: fine) { .card:hover { box-shadow: 0 8px 24px rgba(0, 0, 0, .2); } } ``` This preserves hover feedback while removing repeated shadow painting during an animation. Append this reduced-motion override: ```css @media (prefers-reduced-motion: reduce) { .dropdown, .dropdown.open, .modal, .modal.open { transform: none; transition: opacity 200ms ease; } .popover { transition: opacity 200ms ease; } } ``` One grounded optional addition: give the Menu button press feedback with `.btn:active { transform: scale(0.97); }` and `.btn { transition: transform 160ms ease-out; }`. If adopted, also add `.btn:active { transform: none; }` in [... excerpt: first 3200 of 3496 characters]
