/* headless — marketing site.
 *
 * The design tokens below are LIFTED VERBATIM from web/src/index.css, which is the
 * dashboard's stylesheet. That is the whole point: the landing page and the product
 * must be visibly one thing, so they share a palette, a type stack, a radius and a
 * shadow rather than merely resembling each other. If a token changes in the app,
 * change it here too.
 *
 * Constraints this file is written under, all deliberate:
 *   - NO external requests. No web font, no CDN, no analytics. The system font stack
 *     is the app's font stack, so self-hosting a typeface would make the two LESS
 *     alike, not more. A strict CSP with no third-party origins passes as-is.
 *   - NO build step. This is the stylesheet the browser gets.
 *   - Light and dark, via prefers-color-scheme, exactly as the app does it.
 *   - Every colour used for TEXT clears WCAG AA (4.5:1) against the background it
 *     actually sits on, in BOTH schemes. See the note below — this is the one place
 *     the marketing page deliberately departs from the app's values.
 */

/* ── design tokens (from web/src/index.css) ─────────────────────────────────── */
/*
 * THE ONE DELIBERATE DEVIATION — light-mode text colours are darkened.
 *
 * The app's palette is tuned for 14px UI chrome, where these colours are mostly
 * borders, dots and status badges glanced at, not prose read for a minute. Measured as
 * TEXT against the background it lands on, several of them miss WCAG AA (4.5:1):
 *
 *   #2f80ed accent   white label on the primary button → 3.9:1   (and links on paper)
 *   #2f9e44 green    "Live" pill on its own 8% tint     → 3.2:1
 *   #b8860b amber    "Planned" pill on its own 9% tint  → 2.9:1
 *   #787774 text-dim secondary prose on #f7f7f5 paper   → 4.2:1
 *
 * A landing page is read, at length, by people who may be on a phone in daylight — so
 * each is darkened to clear 4.5:1 while keeping the SAME HUE. Side by side with the
 * dashboard they read as the same blue, the same green, the same ink; a contrast
 * checker sees the difference and passes. DARK MODE IS UNCHANGED: every one of the
 * app's dark values already clears AA against #191919.
