/* ============================================================
   TORII — soul-register slide layouts
   The threshold between speaker and audience.
   Default register: warm bone paper, sumi ink, champagne accent.

   All type / color / spacing comes from tokens. Decks should use
   these classes — inline style is reserved for one-off layout
   overrides that genuinely don't repeat. Editing tokens.css must
   propagate to every slide without touching the HTML.
