- Palette per the owner's hexes: background #141414, raised #1C1C1C, edges #434343, ink tokens, destructs unchanged; :root and .dark carry identical values (the app is always dark). - Type ladder declared once (11px base, each size carries its own line-height); radii ladder 4/8/12/16; spacing rhythm = Tailwind's 4px scale. All documented in the globals.css header. - Fonts: JetBrains Mono (chrome) + Source Sans 3 (prose) via next/font/google in app/layout.tsx; CMU Serif bold bundled locally (public/fonts/cmunbx.ttf) behind the lh-cmu @font-face. - Prose/emphasis tokens: --lh-ink-strong (rust bold), --lh-ink-italic (blue italic), .lh-prose wrapper — ready for the future settings UI. - l.h-ink-strong/italic defaults sampled from the reference mockup.

/*
|
|
* THE SKIN — wave 5. Design tokens, the single place to restyle the app.
|
|
*
|
|
* Mathematical soundness, per the owner's brief:
|
|
* - Tailwind's built-in 0.25rem (4px) spacing scale IS the rhythm — every
|
|
* padding/margin/gap in the app uses whole units of a 4px base.
|
|
* - The type scale below is a declared modular ladder (each --text-* token
|
|
* carries its own line-height); components never invent pixel sizes.
|
|
* - Radii ladder is 4 / 8 / 12 / 16px multiples of the 4px base.
|
|
* - Emphasis colors live in tokens (--lh-ink-strong / --lh-ink-italic) so a
|
|
* future settings UI reassigns them (configurable per the owner).
