 * Layout: an observer's notebook beside the instrument. Copy sits in a
 * narrow reading column; the live pieces (the eclipse, the session, the
 * recall bench) sit beside it or run full width on a raised panel.
 *
 * Color: the A1 Annulus palette. Night ground, Pearl ink, one Periwinkle
 * accent for the bead and for action; light theme on Mist with Ink. Dark is
 * the default look; the system setting picks, html[data-theme] overrides.
 * The three memory networks are told apart by shape (the phases of an
 * eclipse), never by extra hues. Semantic colors (live, stale, orphaned)
 * always travel with a label.
 *
 * Type: Cormorant for display (headlines only, 32px and up), Hanken Grotesk
 * for everything read, DM Mono for records, commands and terminals. One
 * 1.25 scale from 16px; 8-point spacing.
