Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-25 (score 71, +15)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-09-24 (score 56)

First indexed and scored.

## MCP tools (6)

### `audit_css` (~95 tokens)

Audit CSS for the tells that make an interface look machine-generated: framework-default blues, Inter/Roboto stacks, purple-pink gradients, flat type scales, uniform radius and shadow, centred everything. Returns findings with the reasoning and a concrete fix. Run this before calling any UI finished.

Input parameters:

- `css` (string, required): Stylesheet text, a design-token block, or a Tailwind config. Paste the real thing rather than a summary.

### `suggest_fonts` (~135 tokens)

Suggest Google Fonts for a role and mood, drawn from the live catalogue of ~1,950 families. Deliberately skips the overused defaults (Inter, Roboto, Poppins and similar) that make generated UI look generated.

Input parameters:

- `include_defaults` (boolean): Set true to allow Inter and the other signature defaults back into the results. Defaults to false.
- `limit` (number): How many to return, 1-20. Defaults to 6.
- `mood` (string): Visual direction to aim for. Defaults to neutral.
- `role` (string): Where the face will be used. Defaults to body.

### `suggest_pairing` (~59 tokens)

Suggest display-and-body font pairings for a mood, pairing across a category boundary so the contrast reads as deliberate. Returns ready-to-use @import URLs and CSS stacks.

Input parameters:

- `mood` (string): Visual direction to aim for. Defaults to neutral.

### `check_contrast` (~100 tokens)

Score a foreground/background pair for readability. Reports the WCAG 2.2 ratio with AA/AAA verdicts and the APCA Lc value, which is the better guide for dark themes where WCAG 2.x passes pairs that are hard to read.

Input parameters:

- `background` (string, required): Background colour in the same formats.
- `foreground` (string, required): Text colour as #rgb, #rrggbb, or rgb(r, g, b).

### `build_palette` (~105 tokens)

Build a perceptually even colour ramp from one seed colour, in OKLCH. Returns 11 steps with contrast against white and black already computed, plus the CSS custom properties. Use this instead of hand-picking hex values, which produces unevenly spaced ramps.

Input parameters:

- `name` (string): Token name for the generated custom properties. Defaults to 'accent'.
- `seed` (string, required): Seed colour as #rgb, #rrggbb, or rgb(r, g, b).

### `build_type_scale` (~166 tokens)

Build a fluid modular type scale as clamp() values that interpolate with the viewport instead of stepping at breakpoints. The narrow end uses a gentler ratio so headlines stay readable on a phone.

Input parameters:

- `base_rem` (number): Body size in rem. Defaults to 1.
- `max_viewport_px` (number): Viewport where the scale stops growing. Defaults to 1440.
- `min_viewport_px` (number): Viewport where the scale stops shrinking. Defaults to 360.
- `ratio` (string): Scale ratio. Defaults to perfect-fourth.
- `steps_down` (number): Steps below body, 0-2. Defaults to 2.
- `steps_up` (number): Steps above body, 0-8. Defaults to 5.
