/*
  gear.casa design system v2, "data-dense pro" (Style L).
  Locked in 2026-05-30 after iterating across 12 prototypes (see
  planning/prototypes/). Inspired by PCPartPicker / RTINGS / GitHub:
  utilitarian light, blue links, compact rows, table-forward.

  This file is the SEED of the new system: tokens + fonts + base
  components. It will grow as we re-skin the rest of the site.
  Existing pages (home, vertical-category, product-detail, compare,
  search) still use the old styles.css until we port them; only new
  pages link this stylesheet for now.
