/* shared.css — Tooly McToolface v7.41.1
 * Single source of truth for design tokens, @font-face, and common styles.
 * Intended to be linked from every page, eliminating per-page CSS
 * duplication. (Actual duplication delta not measured — to be quantified
 * in v7.42 once per-page linking is complete.)
 *
 * Self-hosted fonts eliminate 2 DNS lookups + external stylesheet request.
 * font-display:swap ensures no invisible text during load.
