/* meetnix.ai — the marketing site.
 * ===========================================================================
 *
 * NO WEBFONT. NO SCRIPT. NO THIRD-PARTY REQUEST.
 *
 * Not a performance preference — the product's entire proposition is that it
 * does not phone anywhere, and this page is evaluated by people inside
 * networks where an outbound request to a font CDN is a finding. So: system
 * faces, inline SVG, and every interaction below (the mobile drawer, the
 * install tabs, the FAQ) is built out of `:checked` and `:target` rather than
 * JavaScript. The page paints in one round trip from one host.
 *
 * THE PALETTE IS brand.html §03, six values, one of them rationed:
 *
 *   Night  #1A2744  structure — chrome, panels, headings on light
 *   Ember  #C4553A  RATIONED — a session in progress, and the primary action.
 *                   NEVER in the mark, never as decoration. If everything is
 *                   accented, nothing is marked.
 *   Ink    #1A1A1A  running text on light
 *   Paper  #FAF9F8  warm ground on light, text on dark — our output is documents
 *   Slate  #5A6B7A  secondary text, metadata, captions
 *   Ash    #E0DDD8  rules and borders
 *
 * DARK IS THE DEFAULT and light is complete. The readers are engineers and the
 * people who fund them; the ground is deeper than Night so that Night can be a
 * *panel* and still separate from it — one hue, two jobs.
 *
 * TWO FAMILIES, and the second one is load-bearing. Everything the product
 * emits is a file, a JSON document or an identifier, so every value that came
 * out of the record is set in mono on this page too. When you see mono here,
 * you are looking at something the software actually wrote.
