/* Renéra · Cookie consent banner (Issue #38)
   Non-modal dialog: desktop = fixed card centred along the bottom edge,
   ≤640px = bottom sheet.
   Tokens only (design-system.css). z-index 9000: above header (50–60) and
   toasts (100), below the mobile menu (9999) and the cart drawer (10000).

   TWO THEME-WIDE RULES REPAINT BARE <button> ELEMENTS, and every control in this
   banner is a <button>. Both must be out-ranked or the banner stops looking like
   the rest of the site:

     1. brand-base.css — `button, [type="button"], [type="submit"], [type="reset"]`
        sets colour/border to the olive fallback, and `button:hover` fills it
        terracotta. `[type="button"]` is an attribute selector: specificity
        (0,1,0), a TIE with a single component class, so this file only wins by
        loading later (see reneranutrition_consent_enqueue, priority 23).
     2. Each page template inlines `body.rn-*-page button { font-family: inherit }`
        — specificity (0,2,1), which NO single class can beat at any load order.

   So the properties those two touch (colour, background, border-colour, font)
   are pinned below under the `#rn-consent` id scope (1,1,0). Keep new controls
   inside that scope, and give every hover state an explicit background — the
   inherited `button:hover` fill is otherwise what paints a text link.
