/* ============================================================================
 * InControl — marketing site stylesheet
 *
 * One file, no build step, no JavaScript. Every page in `site/public/` links
 * this and nothing else.
 *
 * The tokens below are lifted from the APP's design system
 * (src/web/styles/tokens/{colors,surfaces,typography}.css) so the site and the
 * product read as one thing: same Figtree, same warm-paper/cool-ink palette,
 * same Milemark indigo accent, same radii and shadow family, same epic hues.
 *
 * Two deliberate divergences from the app:
 *
 *   1. TYPE SCALE. The app's scale tops out at 28px (`--text-display`) because
 *      its largest text is a project title inside a dense planning surface. A
 *      marketing page needs a display tier above that, so the `--fs-*` ramp
 *      here extends the app's family upward rather than replacing it. Body is
 *      17px, not the app's 15px: reading prose at arm's length is not the same
 *      job as scanning a Gantt lane.
 *
 *   2. DARK MODE. The app is light-only. A marketing site is read in bed, in a
 *      dark terminal-shaped life, and by people whose OS has decided. So the
 *      whole palette is re-declared under `prefers-color-scheme: dark` — same
 *      token NAMES, so every rule below is written once and only once. The dark
 *      values keep the warm/cool split (ink stays faintly indigo, surfaces stay
 *      faintly warm) and lift the accent's lightness, because 50% indigo on a
 *      dark ground is a hole rather than a highlight.
 * ========================================================================= */
