   PIXBOB FONT STUDIO — DOCUMENTATION STYLESHEET
   ----------------------------------------------------------
   Token values below are pulled directly from PixBob Font
   Studio's own app stylesheet, so the docs feel related to
   the app without imitating its editor UI.

   Design note: the three callout types (Tip / Note / Warning)
   are tinted with the exact same colors as the app's own
   canvas guides — Baseline (orange), Max Height (cyan), and
   Left Side Bearing (magenta). In the editor those lines guide
   your drawing; here they guide your reading.

   matching is deterministic (the woff files are static faces):

     • 'PixBob Sans Bold' → Bold,    used for titles & subtitles
