/* Orion Studio Pro: "The Movement" (T386, 2026-10-17). The family frame (header, footer, base, buttons, status line)
   and the direction's tokens. The look comes from the product's features, not the app's colours (the owner,
   2026-10-17): a watchmaker's bench at night. Graphite, polished steel, one ruby accent, cool bench light.
   One family, Neue Haas Grotesk Display Pro, from the owner's font set (brain fonts pair --scenario finance). */
