/* ==========================================================================
   EDITORIAL INK — 1. Foundations
   Tokens, reset, typography scale, shared utilities.

   The palette is defined as *semantic* tokens (--bg, --fg, --accent…) rather
   than literal colours. Any block can flip to the dark treatment by carrying
   .section--ink, which reassigns those same tokens — so every component below
   works on paper and on ink without a single duplicated rule.
