/*
 * Base (issue #43): minimal reset + element defaults on the token system —
 * typography (system font stack), links with visible focus, form controls,
 * table normalization. Visual treatments that are a choice (not a default)
 * are opt-in classes in components.css.
 */

/*
 * The faces, self-hosted (issue #298, doctrine R17 and R18). Literata for
 * reading, Public Sans for headings, IBM Plex Mono for what is raw — all
 * SIL OFL 1.1, vendored under app/assets/fonts with their licence files,
 * served by this relay and never by a third party (AGENTS.md hard rule 8).
 *
 * Chosen on a board, not by taste: docs/design-board-pass1.html narrowed
 * three directions to one, pass1b's matrix put four serifs on our own
 * screens, and pass1c settled the last two at the sizes our voice lives
 * at — 16px prose and 13.6px hints. Literata was drawn for long screen
 * reading, which is what the hints, the posture notes and "what crossed,
 * and what was not learned" actually are.
 *
 * `font-display: swap`: the text is readable in the fallback before the
 * face arrives, because a relay that shows nothing while a font loads has
 * traded a decision's speed for its looks (bible Part VIII).
