/* ============================================================================
   ExamCatalyst AI — bespoke design system, replacing Material's default
   visual language wholesale (content/nav/search engine only kept from
   Material — see mkdocs.yml's own comments for what that split covers).

   Subject: AI-generated study notes/MCQ practice for CSIR NET & GATE
   aspirants — a STEM postgraduate exam-prep audience. Precise, unhurried,
   allergic to fluff, but the marketing surface (home, pricing) should feel
   considered and a little warm — "a serious study desk," not a SaaS
   dashboard.

   Fonts: Fraunces (headings/display — self-hosted, docs/assets/fonts/
   Fraunces.woff2, variable: opsz 9-144, wght 300-700) + Inter (body/UI —
   self-hosted, Inter.woff2, variable: wght 400-800). Both loaded once here
   via @font-face, no external request at all (see overrides/main.html for
   the <link rel=preload> that starts fetching them before this file is even
   parsed).

   Palette: cool paper ground / ink text, a studious indigo-violet accent
   (NOT Material's stock indigo swatch — a custom, slightly more saturated
   violet), and a warm amber "highlighter" mark used only for quota figures,
   the popular-plan badge, and numbered steps — never as a second competing
   accent. Wired to Material's own `[data-md-color-scheme]` attribute (set
   by its light/dark toggle) so theme switching works without any JS of our
   own.
