/* Lalakai article system — long-form posts (blog-hunter-*.html, training notes).
   A static article system built on the
   Lalakai tokens. Font mapping is deliberate, not 1:1: the source runs a
   grotesk for headings and a serif for prose; here `--font-heading` IS the
   serif and `--font-body` the sans, so article headings use the sans stack
   and prose the serif stack. Loaded only on article pages, after
   lalakai-merge.css. */
