/* RailCheck typography (branch typo-gpt): the type scale of _dump/gptypography.md, on the three RailCheck pages only
   (layouts/railcheck/*.html, body.rc), loaded after sim.css and report.css. The labs landing page and the status page
   share sim.css but not this file, so they keep the old sizes; the site header and footer keep theirs too.
   Families stay as _graphic_identity/typography.md has them (sans prose, mono labels and numbers); this file sets
   sizes, weights and line heights only. Drawings keep their own sizes (the board and network SVGs, the 3D labels,
   the report's cover map and landscape cells): their text scales with the drawing. */
