   Quell — Investor Deck · Theme & Design-System (v2)
   Editable source. `build.py` inlines this into dist/ (self-contained).

   Design goals (from Furti feedback):
   - Guaranteed readability: text never sits on a surface lighter than it.
   - Lean slides: one idea + 1–2 lines; detail lives in speaker notes.
   - Real device shown (line-art from official packaging), not a wrong AI render.
   - Touch/phone operable without a keyboard (big on-screen controls, swipe).
