/* ORBIS product site.
 *
 * CON-01 applies here too: no CDN, no external font host, no runtime fetch. Everything below is
 * self-contained, which is why the type stack is system fonts rather than a webfont — a marketing
 * page that cannot be served inside the air gap is a marketing page that contradicts the product.
 *
 * The palette is committed dark. This is a deliberate single look rather than a theme-switching
 * page: the operator client it fronts is dark, and a site that renders light while the product
 * renders dark reads as two different products.
 */

/* ── Typeface ────────────────────────────────────────────────────────────
 *
 * The SAME two faces the Deck bundles, vendored here rather than fetched: Inter for UI text and
 * JetBrains Mono for anything an operator reads as a value. CON-01 is why they are files in
 * `site/fonts/` and not a Google Fonts link — a marketing page that cannot be served inside the
 * air gap contradicts the product it is selling.
 *
 * They matter beyond taste. A site set in the host's default UI font and a client set in Inter
 * read as two different products, and the ORBAT builder sits between the two.
 *
 * Variable weight axis, latin subset, `swap` so text is never invisible while the file loads.
 * Licences: SIL OFL 1.1, both — see `site/fonts/`.

   The direction is **instrument glass**: this page is the illuminated cover over the console it
   fronts. Everything decorative below is derived from something the product actually draws — plan
   grids, orbital rings, a radar sweep, the kill chain — rather than from a stock visual language.
   That is the difference between a page that looks designed and a page that looks *for this*.

   Three rules keep it from tipping into noise:

     1. **One light source.** All brightness comes from the logo gradient. No second accent hue.
     2. **Motion earns its place or it goes.** One orchestrated arrival per viewport, then stillness.
        Nothing loops in the reader's peripheral vision except the hero, which is the only place a
        person is not yet reading.
     3. **Nothing animates that cannot also be static.** Every reveal below is a no-op under
        `prefers-reduced-motion`, and the page is complete without a single frame of it.
   ═══════════════════════════════════════════════════════════════════════════ */
