/* ==========================================================================
   Shared label typography
   --------------------------------------------------------------------------
   The site has many small uppercase mono labels: section eyebrows, tags,
   captions, metadata. They share these typography tokens; each component
   class below adds its own font-size (10px or 11px), color, and decoration.
   Naming is historical (stat-tag / func-tag / .num / .label / .caption /
   .channel etc.) — the shared values live here so changes propagate.

   Outliers preserved separately (intentional, see their own rules):
     .price-note         — 0.04em tracking (descriptive note, not a label)
     .marquee-track span — 12px / 0.2em (decorative scrolling strip)
     .footer-bottom      — fine print, mono but not a label
