/* WatchTower console — "The Calm Watch".
 *
 * A security console that feels like a quiet observation deck at night.
 * Committed dark: one deliberate deep-navy nocturnal world. The identity is
 * ported faithfully from the approved mockup (/tmp/wt_calmwatch_mockup.html)
 * onto the console's existing `.c-*` classes — token NAMES the templates and JS
 * reference are unchanged, only VALUES moved, and new additive tokens/classes
 * were added.
 *
 * Signature hue = azure blue (--c-accent): brand mark, active nav, focus rings,
 * links, primary button, beacon. Blue is now the single brand hue — the former
 * iris secondary is folded into the accent (--c-iris repoints to --c-accent),
 * and the former teal is retained ONLY as the semantic "good / protected" green
 * (--c-good #35d3a6), used sparingly for success states — never as brand.
 * Type is self-hosted (no external calls — CSP `font-src
 * 'self'`): Instrument Serif (editorial display), Hanken Grotesk (body/UI),
 * IBM Plex Mono (numbers/mono). Every existing `.c-*` class, focus ring,
 * reduced-motion guard, mobile rail toggle, the end-of-file cascade fix, the
 * `--wt-rook` mask and tenant `--c-accent` branding are preserved.
