/* Isla Noctura - Proximity Voice (/voice/).
 * Page-local skin on top of the moonlit-island tokens in /css/site.css:
 * near-black navy panels, moonlit silver type, chiselled stone edges, and the
 * site's own signal colours for the connection lamp. The instrument is "the
 * signal": a round transmit key, a level-bar mic meter, mono readouts, and the
 * WITHIN EARSHOT log.
 *
 * Structure, geometry and rule order are the fleet donor's, byte for byte.
 * Only the palette, the two font stacks and this comment differ - see
 * kit\skin_css.py, which asserts the selector set is unchanged.
 *
 * Every id and class the SHARED fleet voice engine drives is styled here; the
 * engine itself is never edited for a design change (canonical rule 6).
