/* Ninna website — calm, reliable, parent-first.
   Single shared stylesheet for the landing + legal + support pages.

   Aligned to the in-app "Parent Comfort" design system:
   - Light (Family Room): warm off-white bg, cream cards, muted sage primary,
     soft peach accent, warm near-black text.
   - Dark (Quiet Nursery): warm near-black bg, charcoal cards, dim sage, soft
     peach accent, cream text. Same structure — only color tokens change.
   Theme follows the OS (System), matching the app's default. */
