/* ============================================================================
   OAKEN MOMENTS — Design System
   Warm editorial. Built for 60+ guests on slow Nigerian mobile connections.

   HARD RULES baked into this file:
     - Base font size is 18px. Nothing user-facing is below 15px.
     - Every interactive target is >= 56px tall (inputs 60px).
     - Focus is always visible, 3px, never removed.
     - No web fonts. System stacks only, so first paint needs zero network.
     - No images in CSS. Total weight target < 20KB gzipped.
     - Colour contrast >= 4.5:1 for text, >= 3:1 for UI boundaries.
   ============================================================================ */
