/**
 * KND Games shell — global header + shared visual primitives.
 *
 * Visual language follows KND Access Gate V2 (assets/css/auth-v2.css): near-black environment, cyan key light,
 * restrained violet rim light, perspective grid, grain, vignette, premium dark surfaces, hairline borders,
 * restrained motion. Auth V2 stays self-contained; nothing here is imported from it and vice versa.
 *
 * Loaded last by generateHeader(), on top of Bootstrap / style.css / knd-skin.css. Header selectors are written
 * with enough specificity (and !important only where the legacy topbar rules use it) to win without touching
 * legacy files. Markup: includes/header.php (generateNavigation) + includes/knd_shell.php.
 *
 *  1. Tokens            5. Account menu        9. Page primitives
 *  2. Header frame      6. Mobile drawer      10. Reduced motion
 *  3. Brand + guardian  7. Chips / CTA
 *  4. Primary nav       8. Environment
