/* co-muse studio tool — "graphite gallery" design system (design_handoff_comuse).
 * The /app surface now shares one visual language with the landing, console and
 * booking widget: near-black graphite with radial depth, silver ink accent #ECEDEF,
 * square corners (only the three-dot logo mark is circular), IBM Plex Mono labels,
 * an Instrument Serif italic accent, tilt + shine-outline cards and magnetic CTAs.
 *
 * Contract note: every class app.js touches (.overlay.open, .toast.in, .drop.drag,
 * .preview.scanning, .segbar/.seg-cell.on, .flag.show, .reveal.in, .pill.done, …)
 * keeps its name and behavior — only the skin changed. The legacy light-theme
 * variable names (--ink, --muted, --line-mid, --field, --paper, --card) are kept
 * and remapped to graphite because app.js emits inline styles that reference them. */
