/*
 * VIP system layer. One copy of what 29 block stylesheets each carry today.
 *
 * The button system lives here as REAL CLASSES. It was a SCSS mixin library,
 * so `@include btn.primary` emitted the whole rule body at every call site -
 * 32 call sites across 9 blocks, all shipping duplicate bytes.
 *
 * Consumes the --vip-* and --brand-* tokens from brand.php. Cosmetic only;
 * anything that decides geometry or visibility belongs in
 * inc/critical-layout.php.
 *
 * The button rules are a faithful translation of
 * src/shared/button/_buttons.scss, declaration for declaration, so moving a
 * block onto these classes is a swap and not a redesign. That includes the
 * `!important` on colour: Astra's `.entry-content a` rules out-specify a plain
 * class, and the mixins have always carried it. Timing is the mixins' real
 * 220ms cubic-bezier(0.2,0.7,0.2,1), not the --vip-dur-* primitives, which no
 * button has ever used - matching the source of truth matters more here than
 * spending a token.
 *
 * Colour tokens are mapped from brand.json by VALUE, not by name:
 *   navy   #0A1633 = --brand-ground-dark   (NOT --brand-action-fill)
 *   blue   #2E69FA = --brand-action-fill
 *   deep   #1B3FA0 = --brand-action-hover
 *   grey   #E9E9E9 = --brand-ground-band
