   Mobile + touch overrides — cmhh22 portfolio
   Loaded AFTER styles.css so overrides win.

   Strategy:
   - Touch / coarse pointer  → disable custom cursor halo
   - ≤ 900px  → tablet-style: collapse extras, smaller paddings
   - ≤ 768px  → mobile: bottom activity bar, slide-in sidebar,
                full-screen copilot, bottom-sheet terminal
   - ≤ 420px  → tighten hero / titlebar / page paddings further
