/* Typography — the native system UI font stack (Apple's SF Pro, then
   Helvetica Neue / Helvetica / Arial). No web fonts are loaded: the platform
   CSP would block an external font stylesheet anyway, and system fonts render

/* ==========================================================================
   Icon font — Phosphor Icons (Light weight)
   The theme's small UI glyphs (language globe, nav caret, CTA/pagination arrows,
   the mega-menu and leaf-card arrows) used to be raw Unicode/emoji characters,
   which render inconsistently across platforms. They are now a single bundled
   icon font instead. This is NOT a text web font and does not contradict the
   system-font typography note above: it is Phosphor's Light-weight icon set,
   self-hosted from the theme's own assets and served same-origin, so the
   platform CSP (`font-src 'self'`) allows it and no external request is made.
   Only the handful of glyphs the theme actually uses are mapped below; the full
   Phosphor class list is intentionally omitted to keep the CSS small.
   Codepoints come from @phosphor-icons/web (Light) selection.
