/* ============================================================================
 * Zimac UI — the internal bootstrap.
 *
 * One stylesheet, shared by every internal front end (the proxy, metrics, auth,
 * payments, and whatever comes next) so they read as one product. Think of it
 * as our Bootstrap: design tokens + a small library of components, all using
 * plain semantic class names so a page is mostly markup.
 *
 * The visual language is lifted straight from the Axon/Stitcher desktop app
 * (apps/desktop/public/style.css): charcoal surfaces, the #6c63ff indigo
 * accent, the sage→indigo gradient wordmark, a faint "constellation" glow in
 * the canvas, glassy panels, and soft indigo glows on anything interactive —
 * tuned down to read as calm internal tooling rather than a chat surface.
 *
 * Before this file, metrics/ and auth/ each re-derived these tokens by hand and
 * drifted apart (bg #0f1117 vs #0e0f13, --text-muted vs --muted, …). This is
 * now the single source of truth; every token below is published under *both*
 * naming conventions those services used, so either spelling keeps working.
 *
 * Usage:  <link rel="stylesheet" href="/zimac-ui.css">
 *         (services serve it from zimac_common::ui::STYLESHEET)
 * ==========================================================================*/
