   New classes introduced by /guides/ and /standards/ templates.
   Uses var(--token, fallback) throughout — if your ink/redline token file
   already defines --ink / --redline / --paper / etc., these inherit them
   automatically. If names differ, the fallback values keep this correct
   on its own; just re-point the var() names to match your actual tokens.
