/* ORBIT Brand Components — Canonical v3.0.1
 * Component library CSS — extracted from Infinite People strategy dashboard (Brain v2.0-final)
 * + ORBIT MARK extracted from Supply Doc R-002 (Internal S049, 2026-05-06)
 * Requires tokens.css — load that first.
 * Last updated: 2026-05-06 · Internal S049 · ORBIT MARK component added
 *
 * Components included: orbit-mark · panel · pill · tabbar · masthead · countdown · signal-card · cmd-button · gate
 * Deferred to v3.x: spine-timeline · orbital-action-card · drawer · full command-palette
 *   (those live in IP dashboard code as reference implementation; canon extraction follows with more tenants)

/* ============================================================
 * ORBIT MARK — canonical compact wordmark (HTML/CSS form, dot-in-O)
 *
 * The canonical compact form of the ORBIT wordmark, in HTML/CSS. For SVG
 * variants see orbit-logo.svg / orbit-mark.svg / orbit-wordmark.svg.
 * For the 3D hero variant see orbit-wordmark-3d.jsx.
 *
 * Canonical pattern locked Internal S049 (2026-05-06), extracted from
 * Supply Doc R-002 Engagement Architecture as the cross-tenant reference.
 *
 * Usage:
 *   <div class="orbit-mark" role="img" aria-label="ORBIT">
 *     <div class="orbit-mark-text">
 *       <span class="orbit-mark-O">O<span class="orbit-mark-dot"></span></span>RBIT
 *     </div>
 *   </div>
 *
 * Notes:
 *   · Wordmark typography is fixed ('Space Grotesk') — does not shift with body
 *     font evolutions. The wordmark is a brand identifier, not body copy.
 *   · Dot uses var(--accent) — recolours with brand accent if ever shifted.
 *   · Animation: orbitSpin 2.4s linear infinite (clockwise). Locked invariant.
 *   · Reduced-motion override moves the dot to its rest position (top of O).
