/* render_cluster.py supplemental stylesheet — additive only.
   styles.css (emd-deployer skill file) is never modified; this file only
   ADDS rules for the page types render.py doesn't know about (about page,
   Knowledge Hub, standalone article pages). Reuses styles.css CSS custom
   properties (--primary, --accent, --serif, --sans, --rule-light, etc.)
   so these pages inherit the same per-domain color/font fingerprint as
   the homepage. */
