/*
 * APEX design system.
 *
 * Tokens + cross-page primitives. Page-specific layout stays inline in
 * each page's own <style> block.
 *
 * Typography intent: an institutional terminal, not a consumer
 * dashboard. Prose/labels use a humanist grotesque; every NUMBER uses a
 * tabular monospace so digits align in columns and a changing price does
 * not make the row jitter. Fonts are resolved from the system stack -
 * no webfont is downloaded, so the platform stays fully offline and adds
 * no render-blocking request. On macOS this resolves to SF Pro / SF
 * Mono, which are genuinely high-quality faces.
 */

/* ═══════════════════════════════════════════════════════════════════
 * APEX V3 — "ORBITAL INSTRUMENT"
 *
 * The concept, so every value below has a reason:
 *
 *   APEX is not a dashboard. It is an INSTRUMENT TRAINED ON THE PLANET.
 *   The world is rendered in near-black void; the interface is machined
 *   from titanium hairlines and smoked glass FLOATING ABOVE it.
 *
 * Three laws:
 *
 *   1. SURFACES CATCH LIGHT, THEY DO NOT EMIT IT. Every APEX surface has
 *      a lit top edge and a shadowed underside, as though lit from above
 *      by a single hard source. Nothing glows. A glowing box is a game
 *      HUD; a lit edge is machined metal. This is the most recognisable
 *      trait in the system.
 *
 *   2. ONE ACCENT, SPENT SPARINGLY. Electric ice. It marks what is
 *      INTERACTIVE or what the system is ASSERTING — never decoration.
 *      Gold is RESERVED for gold-market information and is used nowhere
 *      else, so that when gold appears it MEANS gold.
 *
 *   3. TYPE SPLITS BY AUTHORSHIP. Editorial display type for statements
 *      APEX makes about the world; tabular monospace for anything the
 *      MARKET determines. The two never mix inside one line.
 * ═══════════════════════════════════════════════════════════════════ */

 *
 * Surface treatment, motion, navigation and modals — shared by all five
 * pages so they stop looking like five separate builds.
 *
 * Three rules govern everything below:
 *
 *   1. MOTION IS FEEDBACK, NOT DECORATION. Every transition here is
 *      triggered by something real: a page arriving, a pointer entering,
 *      a NUMBER THE BACKEND ACTUALLY CHANGED. Nothing loops forever to
 *      look busy, and nothing animates to imply activity that isn't
 *      happening. A perpetually shimmering panel on a dead bridge is a
 *      lie told in CSS.
 *
 *   2. TRANSFORM AND OPACITY ONLY. Both are compositor properties, so
 *      animation never triggers layout and never competes with the
 *      globe's WebGL frame budget or the chart's tick path.
 *
 *   3. REDUCED MOTION IS HONOURED COMPLETELY (see the end of this file).
 *      Not damped — removed. Final states stay identical, so nothing is
 *      ever left invisible or unreadable.
 * ═══════════════════════════════════════════════════════════════════ */

   V3.1 — SHARED CHROME UPGRADE
   ------------------------------------------------------------
   One header, one card language, one control language across the
   landing page AND every application page (Command Centre, APEX
   Intelligence, Trade Lab, Strategy Lab, Broker Accounts, auth).
   mountShell() renders .apex-header on all of them, so restyling it
   here is what makes the product feel like a single system rather
   than a marketing page bolted to a tool.

   Appended, not edited in place: the existing rules above stay the
   base, these refine them.
