/* ============================================================
   The 66th — Shared Canonical Stylesheet
   ============================================================
   Single source of truth for tokens, base styles, type system,
   layout primitives, and chrome components (nav, marquee,
   section heads, footer, CTA, utilities).

   Page-specific styles stay in each page's inline <style> block.

   FONT SIZE CONTROL
   -----------------
   The entire type system scales from `:root { font-size }`.
   Change ONE value to scale every body text size site-wide.

      :root { font-size: 16px }   ← default
      :root { font-size: 17px }   ← +6.25% bigger everywhere
      :root { font-size: 15px }   ← -6.25% smaller everywhere

   All component font sizes use rem. Display/hero sizes
   stay in clamp(px, vw, px) since they're viewport-relative.
