/* KnowledgeBase — v2 UI (teal terminal / dashboard hybrid).
   Persistent left sidebar, rounded translucent cards, teal→cyan gradient
   accents, monospace terminal cues (> eyebrows, mono metadata, blinking caret).
   Fonts: IBM Plex Sans (UI/prose) + IBM Plex Mono (labels/meta/bodies), vendored.

   Two theme variables: --ac (accent, teal or cyan — set at runtime by
   terminal.js and persisted) and --hi (highlight cyan, constant). Every other
   translucent border/fill is fixed teal, exactly as the design specifies, so
   the tint switch only ever moves the gradient + accent hues. */
