/* =================================================================
   Inkline — playpalapps.github.io/Inkline
   Production-polish sumi-e website. Pure CSS, no build step.

   Design principles:
     • Restraint over richness. Whitespace does most of the work.
     • Three letter-spacing values, three weights, two type sizes per role.
     • Vermillion only as a single accent — never as fill.
     • Movement only where it carries meaning (petals drift, enso breathes).
     • Long-form pages get a sticky TOC on desktop, collapsing on mobile.
