/*
 * ============================================================================
 *  RtfPage.css  — Component-scoped styles  (v3 — full improvement pass)
 *
 *  Changes vs v2:
 *  ✓ Tokens merged into one .rtf-one-page declaration (no duplicate selector)
 *  ✓ Font-size token scale  (--rtf-text-2xs … --rtf-text-lg)
 *  ✓ Surface + ink token scale  (replaces ~40 raw hex values)
 *  ✓ Z-index token stack  (--rtf-z-backdrop … --rtf-z-dialog)
 *  ✓ --rtf-slots-w token for fixed slot-panel width
 *  ✓ `contain: layout style` on every pane for paint isolation
 *  ✓ `transition: all` → explicit property lists everywhere
 *  ✓ `flex: 1 1 0` removed from gallery-scroll (was a grid child — no-op)
 *  ✓ Firefox scrollbar-width / scrollbar-color on all scroll containers
 *  ✓ scroll-padding-top on slot-scroll (keyboard focus no longer clips)
 *  ✓ focus-visible rings on ALL interactive elements
 *  ✓ @supports guard for backdrop-filter  (older Safari fallback)
 *  ✓ @supports guard for color-mix        (Safari < 16.2 fallback)
 *  ✓ 900 px breakpoint: grid-column / grid-row resets added (were missing)
 *  ✓ Dark-mode token layer  (prefers-color-scheme: dark)
