/* Theme: default-02 — "operations console".
   default-02 is the live iteration target. When it improves, keep default-01 in
   sync by copying this file over it:
     cp src/client/themes/default-02/theme.css src/client/themes/default-01/theme.css
   (default-01 is an exact copy; the two must render identically.)
   The design reads like an internal productivity suite:
     - light-gray canvas with pure-white content panels (no colored tinting),
     - deep navy accent with square-ish radii and hairline dividers,
     - category sections as two-column rows: a micro-label column + card grid,
     - tool cards as horizontal rows (icon chip left, text right) that highlight
       on hover instead of boxed cards with lift,
     - a slim accent strip across the very top of the page,
     - the whole UI set in self-hosted Varela Round (rounded, friendly).
   Same HTML, same CSS variables; only the rules differ. Both color modes keep
   identical component rules; only the variables change under the dark query. */

/* Self-hosted Varela Round (OFL-1.1) as the console typeface. Subsetted
   WOFF2 (latin + common punctuation/symbols), copied from the shared
   src/client/fonts/ next to theme.css by the build so this relative url()
   resolves on the home page and in every tool mini-site. Varela Round ships a
   single Regular weight; heavier weights are synthesized by the browser, and
   the missing ✓/← glyphs fall back to the system stack. */
