Tokens

Semantic colors and radii come from the active file in tokens/themes/ (per data-theme). Structure (typography roles, motion, spacing, elevation) lives in tokens/design/.

Colors

Semantic colors for the active theme. Use the toolbar toggle for light vs dark mode.

Semantic spacing

Intent-named tokens in tokens/design/spacing.css. Shifts with data-density and data-gutter.

--space-px

1px; use in CSS. Default Tailwind p-px applies the theme scale.

var(--space-px)

--space-gutter

Control and dense surface padding (data-density).

p-inset-tight

--space-inset

Default padded surfaces such as cards (data-density).

p-inset

--space-inset-loose

Roomier than inset; 1.2× card padding.

p-inset-loose

--space-cluster

Tight rows: chips, icon + label (data-density).

gap-cluster

--space-stack

Default vertical or horizontal gap between siblings.

gap-stack

--space-section

Major block separation; section vertical rhythm.

mt-section

Spacing

Tailwind numeric step scale (rem multiples of 0.25). Prefer semantic spacing when the intent is fixed (gutter, section, card inset).

Elevation

Motion

Durations, easings, composed transitions, geometry, placeholders, and app `animation` shorthands. Keyframes for `--app-*` come from `tw-animate-css` (enter, exit, accordion-*, caret-blink). Primitives also use `animate-in`, `zoom-in-95`, etc. Clamped by `prefers-reduced-motion` in `tokens/motion-reduced.css`.

Text gradients

Headline emphasis only — one phrase per title. Utilities clip gradient fills to glyphs and loop slowly via `text-gradient-shift`; static fallback when `background-clip: text` is unsupported or `prefers-reduced-motion` is on. `bg-gradient-*` reuses the same stops for spotlight card surfaces. Source: `tokens/design/text-gradients.css`.
