/* Content Bridge — interface styles.

   Design rules this file follows:
   - one neutral ground, white cards with a visible edge and a soft shadow, so
     every widget reads as an object sitting on a surface;
   - two text tiers only (ink and secondary), plus a tertiary for timestamps;
   - no interface text smaller than 12.5px;
   - every text colour clears 4.5:1 on every surface it can sit on, in both
     themes. The values were measured; re-check before nudging one.            */
