   Yolt v11 — CD-5 Round 4 polish (D-N31).

   Visual primitives for the polished renderers:
     §1 page-hero-traffic-light → .tone-{good,warn,bad} + .is-active + 3D glow
     §2 power-metrics-bar       → .pm-ic stroke-icon slot
     §3 page-structure-template → .ps-zone / .ps-thumb thumbnails
     §4 page-warning-banner     → .wb.tier-{info,warn,bad,critical}
     §5 modal.critical-kpi-alert → .alert-modal + .alert-scrim + .alert-big-ic

   All colors via oklch tokens (CLAUDE.md hard rule). Animations defined
   у styles/tokens.css (--anim-* tokens). Pull this file AFTER tokens.css
   у v11/index.html + every page template.
