/* Predis Staging Deployer — dark, dense, deliberately a little futuristic.
 *
 * Design rules this file holds itself to (docs/design.md section 8.0):
 *
 *  - Status is never carried by colour alone. Every unit state pairs a colour
 *    with a glyph and a text label, so it survives colour-blindness and a
 *    screenshot pasted into Slack.
 *  - Status colours are a reserved set (running / warning / failed / inert) and
 *    are never reused as decoration. Decoration uses the cyan/violet accents.
 *  - All body ink clears WCGA AA against all three surfaces. --ink-dim is
 *    UI-level contrast only (~3.7:1) so it is restricted to borders, rules and
 *    icons — never small text.
 *  - Motion is ambient, never on a destructive path. The force-reset control is
 *    deliberately plain and slightly severe.
 *  - Everything animated is disabled under prefers-reduced-motion; colour and
 *    layout carry the same information without it.
