   DASHBOARD ▸ OVERVIEW — MITRE ATT&CK insights (ovi-*), rendered by
   dashboard-overview-sections.js. Lives inside .ovx, so it reuses the card
   and chart primitives from dashboard-overview.css; the rest is --theme-*.
   ATT&CK uses ONE sequential hue (--ovv-att), never red/green: steel blue,
   inspired by the ATT&CK matrix itself (attack.mitre.org draws it in slate
   text with steel-blue technique links, #3F709E). Its orange/red brand
   colours are not used — they mean severity here.
