/*
 * Watchtower — design tokens (dark, safety-critical).
 * Per AUDIO_VISUAL_SPEC.md §Activation theming, the top strip and
 * incident cards shift hue based on the current activation level.
 * Tokens here cover the foundation surfaces; module-specific tokens
 * (incident cards, board displays, comms tiles) layer on top.
 */
/*
 * Canonical token set ported from the design handoff
 * (FOP Portal/styles/watchtower.css). These are the names the
 * identity surfaces from src/wt-identity.jsx reference. They
 * coexist with the legacy --wt-* tokens used by the Pass 1
 * shell + foundation page; both sets stay valid simultaneously.
