/*
 * Savanna Time — landing site styles.
 *
 * A deliberate parallel copy of the token values in `web/src/app/globals.css`
 * (the same precedent as `desktop/src/App.css`): the three front ends share no
 * package, and inventing one for a palette would be the larger change. If a
 * token changes in the web app, change it here too — the values are named
 * identically to make that a mechanical diff.
 *
 * ---------------------------------------------------------------------------
 * SIZING: every dimension is `rem`, and every value is the design canvas's
 * pixel / 12.5.
 *
 * The canvas was drawn at a scale where body copy measured 12.5px. This sheet
 * originally transcribed those pixels verbatim — 9.5px chips, 10px section
 * labels, 13px body — while hand-patching only `body` to 15px. The result was
 * the defect the web app carried before it was rescaled: type rendered at
 * roughly 78% of a browser's 16px default, so the page only looked right at
 * 125% zoom, with the half-patched body leaving the ramp internally
 * inconsistent on top of that.
 *
 * Dividing by 12.5 makes `--text-body` exactly 1rem and preserves every ratio
 * between steps — a rescale, not a redesign. Spacing, radii and fixed widths
 * are converted by the same factor, so the layout keeps the canvas's
 * proportions rather than crowding against newly larger type. (The web app got
 * that for free: Tailwind's spacing scale was already rem.)
 *
 * `rem` rather than `px` so the page also honours a reader who has set a larger
 * default font size; a px ramp silently ignores that preference.
 *
 * Exceptions, deliberately still px: hairline borders and the 1px ribbon gap,
 * which are meant to be one device pixel and become a sub-pixel mess in rem.
 * `letter-spacing` stays in `em`, which is already relative.
 * ---------------------------------------------------------------------------
 *
 * Dark mode follows the OS via `prefers-color-scheme`: a marketing page has no
 * account to remember a preference for, so a toggle would be state without an
 * owner.
 */

/*
 * Typefaces. The same three families the web app and the desktop app use —
 * IBM Plex Sans for text, IBM Plex Mono for every figure and micro-label,
 * Instrument Serif for display. Vendored here rather than fetched from a font
 * CDN, so loading a page tells no third party that you did.
 *
 * `ibm-plex-sans-latin.woff2` is a VARIABLE font carrying a `wght` axis from
 * 100 to 700, and the declared range has to say so. It previously claimed
 * `400 600`, which quietly capped `<strong>` and `<b>` — both weight 700 by
 * default — at 600, so bold text on this site was a step lighter than the same
 * markup in the app. The mono and serif files are single static weights, so
 * they are declared as exact values.
 *
 * `font-display: swap` matches the web app: on a marketing page, text that is
 * readable in a fallback beats text that is invisible while a font loads. The
 * desktop app uses `block` instead, deliberately — a flash of fallback inside
 * an application shell reads as a glitch rather than as progress.
