   NERVEASE — custom design system
   FIRST nerve-support site (new category; distinct from all prior).
   "NervEase" = nerve + ease -> calming neural aesthetic.
   Palette: teal-blue #134e5e | violet #8a7fb8 | coral #f2795b
            deep-teal #0d3a46 | cream #f5f7f8 | stone #5e6a70 | line #dde6e8
   Display: 'Bricolage Grotesque' -> soft-modern. If unavailable fallback
            'Poppins'. Use 'Poppins' (rounded, calming, not yet used much).
   Body:    'Inter' -> fallback system
   Signature: nerve calm (a jagged nerve-signal that settles into a smooth
              calm line — nerve irritation easing into comfort)
   NOTE: grids minmax(0,1fr); flex min-width:0; imgs min(NNNpx,100%);
         hero mobile order H1->img->rest.
   Product CAPSULE (2/day with water & meal).
   IMPORTANT: NERVE / PAIN = SENSITIVE health category:
   - NO sciatica/nerve-disease diagnose/treat/cure claims; comfort/mobility
     structure-function ONLY. Not a substitute for medication/medical care.
   - Corydalis + California Poppy + Passionflower are calming/sedative ->
     STRONG sedative/CNS-depressant + alcohol + sedative-med interaction
     (drowsiness) warning. Corydalis + Cal Poppy -> pregnancy AVOID.
   - Source "MD/doctor-reviewed (Irene Paragas)" persona NOT reproduced
     (no fake real-person endorsement).
   - Source's 4.9/12,237 rating softened. NO guaranteed pain-cure in
