/* =========================================================================
   TADABBUR.CSS v2 — Interactive Verse Contemplation Widget
   =========================================================================
   Victorian newspaper aesthetic matching The Daily Revelation.
   Uses revelation.css design tokens: --rev-bg, --rev-ink, --rev-ink-soft,
   --rev-gold, --rev-gold-dark, --rev-surface, --rev-border, --rev-muted,
   --rev-fs-sm, --rev-fs-base, --rev-fs-md.
   Fonts: Playfair Display (headings), EB Garamond (body),
          Amiri (Arabic), Inter (UI).
   All animations: opacity + transform only (GPU-composited).

   v2 CHANGE: Phases use display toggling instead of absolute positioning
   to prevent content clipping on mobile viewports.
