/* ============================================================
   thirdteeth.com — design system
   One neutral light surface (no cream, no black):
   · Publication ground — neutral white, ink text, red #b33a24 accent
   · Panels / reading-room sections — light gray wells, same accent
   · Pink #FF5CA8 survives only in the dashed third-tooth brand mark
   Tier is a density, not a colour: a fixed 5-step gray→white scale.
