/*
 * Self-hosted typefaces, linked by every page the app serves.
 *
 * SPEC 7: "Fonts are self-hosted, not loaded from Google, so client sessions make no third-party
 * requests." The sample (`Hofincons Engagement Gantt.html`) reaches Google Fonts for Barlow,
 * Barlow Semi Condensed and IBM Plex Mono; the product must not, and `security-headers.ts`'s
 * `font-src 'self'` would block it anyway. Bitter is SPEC 7's heading face for the application
 * shell.
 *
 * The files come from the `@fontsource/*` packages (all SIL Open Font License 1.1), latin subset
 * only, copied into `dist/client/fonts/` by `scripts/copy-client-assets.ts` — which reads the
 * `url()` references below as its own list of what to copy, so this file is the only place the
 * bundled set is written down. Weights are limited to the ones the product actually asks for:
 * Barlow 400/500/600, Barlow Semi Condensed 500/600/700, IBM Plex Mono 400/500, Bitter 400/500.
 *
 * `unicode-range` is @fontsource's own latin range, so a character outside it (any non-latin
 * script) falls back to the reader's system font rather than rendering as a missing glyph.
 * `font-display: swap` keeps text readable while a face is still arriving.

/*
 * The font stacks the rest of the stylesheets reference, so no other rule names a typeface

 * (SPEC 5.6, used by the chart surface); `--font-heading` is SPEC 7's Bitter and
 * `--font-shell-body` SPEC 7's "Body: Helvetica, Arial", both for the application shell
 * (`app-theme.css`). The shell's body face is deliberately the reader's own Helvetica/Arial
 * rather than a bundled one — SPEC 7 names those two by name, and neither ships as a webfont.
