   Pastel web UI — M5 "hella cute" visual pass.
   Layered over the functional shell from M2-M4. All element IDs/hooks the JS
   relies on are unchanged; this file is pure presentation + animation.
   Typography: Mochiy Pop One (headings/logo) + Nunito (body) from Google Fonts
   with a system fallback, so it still reads fine fully offline. Mochiy is a
   single-weight face, so heading rules use its natural weight (no font-weight
   bump, which would trigger ugly faux-bold synthesis).
