/* ===========================
   AI FOR REAL LIFE — STUDENT HUSTLE EDITION
   Design System · "Dark-first, warm-accented, sharp-edged"
   ===========================
   Refresh date: 2026-04-25 (post-audit redesign)

   DESIGN INTENT
   - Dark by default (students study at night; cream glows at 1am)
   - Light mode available via [data-theme="light"] (sharp white, NOT cream)
   - Terracotta accent kept for family coherence with the Mom Life edition,
     intensified from #c47a5c to #e8794a so it pops against deep neutrals
   - Soft shadows replaced with crisp 1px borders + selective glows
   - Cream-on-cream gradients removed
   - Type contrast pushed harder (cream on dark / near-black on light)
   - Instrument Serif + Outfit retained — they were already working
   - Family lineage: same component class names as the Mom Life edition
     so HTML stays portable; just the visual layer rotates.
