/* ============================================================================
 * site.css — Odimba Technology
 * ----------------------------------------------------------------------
 * ONE stylesheet for the entire public site (the old site duplicated a
 * ~150-line <style> block across all 14 pages — see chat notes). Loaded
 * once via partials/head.php and long-cached (see root .htaccess).
 *
 * Deliberately uses the OS system font stack rather than custom webfonts:
 * zero extra network requests, zero render-blocking @font-face, and it
 * still looks sharp on every platform. This is one of the biggest single
 * levers for the "as fast as possible" goal — a custom webfont is
 * routinely 100-300KB+ and blocks text rendering until it loads.
