- The hidden fourth font: Tailwind's font-mono/font-sans utilities fall to the SYSTEM stacks (SFMono/Menlo — a font the app never chose), and streamdown's code-block chrome, mermaid-error, and the demo-card meta all use them — so every teaching-prose code block rendered in the system mono. Fixed at the token level: @theme now aliases --font-mono → JetBrains Mono and --font-sans → Source Sans 3, so every utility use resolves to the app's three fonts (chrome=JetBrains, prose=Source Sans, display=CMU bold). - Session titles: Source Sans 3 (the human-words voice — the same font the words were typed in; mono = machine data stays on the meta line). One rule, finally applied to the picker too. CMU bold titles are the queued experiment if this reads wrong live. Gates: typecheck, lint, 469/469. Live: title "Source Sans 3" 12.5px, meta "JetBrains Mono" 11px; code blocks now JetBrains.

* 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).
