   e-Vāgbhaṭa -- design tokens
   Palette drawn from palm-leaf manuscripts: aged-paper ground,
   warm ink, and the terracotta "rubrication" red traditionally
   used for chapter/verse numbering. Same tokens as the e-Suśruta
   and e-Caraka sites in this family, for a consistent look.
   Type: Gentium Book Plus throughout (SIL font built for full
   IAST diacritic coverage) -- one family, two weights, so long
   Sanskrit passages never risk a missing-glyph fallback.

   Root text (Aṣṭāṅgahṛdaya) is set larger at the full measure.
   The two commentaries are both set smaller and indented behind a
   rule, matching print convention, but the rule colour differs
   (muted tan for Aruṇadatta, gold for Hemādri) so the two are
   distinguishable at a glance even before reading the "Sa." /
   "Ā. rā." label -- useful since Hemādri's commentary is only
