 * BetAlert Brand v2 — shared public shell (navigation, mobile menu, footer).

 * Load after css/style.css and css/brand-v2.css. Tokens come from brand-v2.css

 *
 * Deliberately unlayered: legacy style.css is unlayered, so layered rules
 * (including .bv2-button primitives) would lose to its element resets such as
 * `* { padding: 0 }` and `a { color }`. Every selector here is anchored to a
 * .bv2-header / .bv2-footer root so nothing reaches legacy page bodies.
