   Vostego Utilities — Tailwind-convention helper classes
   Several pages were authored against Tailwind utilities that this
   site never shipped; this file provides the subset actually used.
   Values follow the Tailwind 4px scale, mapped to refined tokens
   where they coincide. Additive only: nothing here hides content
   (no .hidden — pages define their own where step logic needs it).
