/* Preamble — FLAT DESIGN SYSTEM (sleek modern flat, NOT AI-slop)
 * ───────────────────────────────────────────────────────────────────────────
 * SURFACES: solid opaque elevation fills (no translucency).
 *   Dark:  --bg-0 #090d18 canvas; --surface #131a2b (cards/chips/inputs);
 *          --surface-2 #1a2236 (nested/active/logos); --surface-3 #232c43
 *          (highest inline/active segmented); --bg-1 #0e1424 (modal body/wells);
 *          --bg-2 #141b2e (code).
 *   Light: --bg-0 #eef2f9 canvas; --surface #ffffff; --surface-2 #f1f5fb;
 *          --surface-3 #e6ecf5; --bg-1 #f4f7fc; --bg-2 #e9eef6.
 * BORDERS: --border is TRANSPARENT (cards/chips/buttons have NO border).
 *   --hairline = ONLY for inputs (resting) and inline code.
 *   --divider  = ONLY for MAJOR pane seams (topbar/body, sidebar/main,
 *                modal header/footer, section bands, table header→rows,
 *                console nav/main).
 * NO decorative gradients. Progress/meter/adoption/spend bars = SOLID
 *   var(--accent) (or var(--cyan) for a 2nd series; semantic green/amber/rose
 *   for status). SVG area-chart fades (data viz) are OK.
 * NO glows. No --accent-glow box-shadows. One soft elevation shadow
 *   var(--shadow-md) ONLY on true overlays (modals/menus/popovers); none on
 *   inline cards. Keep the .dot.live green pulse (sanctioned functional glow).
 * NO backdrop-filter anywhere EXCEPT .modal-backdrop scrim.
 * RADIUS: --radius-sm 8 (chips/inputs/icons); --radius 12 (cards);
 *   --radius-lg 16 (modals); --radius-pill 999. Retire 22px/ad-hoc radii.
 * IDENTITY: navy base, electric-blue var(--accent) primary, var(--cyan)
 *   secondary, green = STATUS ONLY. Fonts unchanged.
 * HOVER = elevation step (surface→surface-2) + optional translateY(-1px);
 *   never a glow/border.
