/* Neumorphism Revisited — soft extruded surfaces, with the contrast fixes neumorphism usually skips.
   Rules this file enforces:
   1. Text is never tone-on-tone: ink is 13:1+, secondary ink 7:1+ on the ground.
   2. Every control carries a 3:1 edge line, so it is findable without the shadow.
   3. Current / pressed / selected always pair the inset shadow with a second cue (weight, dot, check).
   4. Primary actions are filled, not extruded.
   5. A "Crisp" depth mode (and prefers-contrast: more) trades blur for hard edges. */
