/*
 * Sanadat marketing site: one stylesheet, no build step, no external requests.
 * - Mobile first. Layout uses logical properties (inline/block, start/end) so the same rules serve
 *   Arabic (dir="rtl") and English (dir="ltr"). Physical properties appear only where a shape is drawn.
 * - The look is the app's (web/src/styles/base/tokens.css): brand blue, the same ink and lines, small
 *   corners (cards 6px, buttons 2px), Plus Jakarta Sans for Latin and Cairo for Arabic.
 * - Colours are custom properties on :root; the dark theme redefines them under prefers-color-scheme.
 * - The home page is deliberately short: on a laptop everything fits on one screen.
 * - Contrast: body text, muted text, brand text and button labels are all at least 4.5:1 in both themes.

/* ---------- Fonts (SIL OFL, see assets/fonts/OFL.txt) ----------
   Both are variable fonts (one file serves every weight), copied from web/src/styles/fonts. The stack
   resolves per glyph, as in the app: Latin text and digits use Plus Jakarta Sans, Arabic uses Cairo.
   unicode-range keeps each file to the pages that show that script (an English page fetches Cairo
   only for its "العربية" link). */
