/* RapidTablet design tokens + base components (v3)
   ------------------------------------------------------------------------------------------
   Light "paper" theme is the default; dark is opt-in with <html data-theme="dark">.
   Rules of the system:
   - One accent. Orange is for the primary action on a screen and for flags. Nothing else.
   - Lime belongs to the character and the live indicator only.
   - Navy is the ink and the top bar.
   - Sentence case everywhere. Hierarchy comes from size and colour, not from bold or caps.
   - 8 px grid (4 px only for optical nudges inside components).
   - Hairlines between things, not boxes inside boxes.
   - Touch targets 44-56 px tall that do not look like toy buttons.
   - No animation except the character's 2 fps pen tick / blink (steps(), ~0 CPU).
