/*
 * Wanis OS landing page — DARK, in the brand's own palette, for all three locales.
 *
 * ## Where the colours come from
 *
 * Sampled from the operator's brand artwork, not invented: lime `#b7ff1d` with `#8ad004` for its shaded
 * face, graphite `#43474a`…`#5c6165`, on near-black `#0d1114`. The mark was drawn for a dark ground, so
 * the page is dark — a lime logo floating on white reads as a mistake, and lime on near-black is the
 * pairing the identity was designed around.
 *
 * ## Lime is never used for small text
 *
 * `#b7ff1d` on `#0d1114` is roughly 16:1, excellent. But lime as TEXT on a light chip, or thin lime
 * type, would fail. So the rule this sheet follows is: **lime is for fills, rules, icons and large
 * display type; prose is white or grey.** Buttons are lime with near-black text, which is both the
 * highest-contrast pairing available and unmistakably the brand.
 *
 * ## Written in LOGICAL properties
 *
 * Every margin, padding and alignment is `inline-start`/`inline-end`/`start`, so Arabic is genuinely
 * RTL rather than a mirrored copy that breaks the first time a section is added without an override.
 *
 * ## No font, no framework, no build step
 *
 * A web font is a third-party request on the critical path; the page must render from one small HTML
 * document. The system stack below covers all three locales, Arabic face included.

   * The forest tones are the brand's second register: the lime is the signal, the forest is the ground
   * it grows out of. They are deliberately kept at low luminance and low saturation so that a page
   * built on them is *deep* rather than merely green — the lime accent is what makes it read as the
   * brand, and a wash of bright green would drown the logo that gives the palette its point.
   *
   * Used for: section grounds and their gradients, card borders on hover, the closing band, and the
   * subtle tint inside panels. Never for text, because at these luminances it fails contrast.
