/* releases.gestalt — Admin-UI (ADR-011, F13).
 *
 * Series design language. The Studio's back-office apps (ops.gestalt,
 * releases.gestalt, …) are one product family and are meant to be recognised as
 * such: same monochrome slate base, same hairline borders, one single elevation
 * (shadow-card), colour used ONLY as status semantics, same shell (fixed 240 px
 * sidebar + translucent sticky topbar + breadcrumb), same control metrics.
 *
 * Source of truth for the language:
 *   ops.gestalt  client/tailwind.config.js   (brand scale, status, shadow, radius)
 *   ops.gestalt  client/src/index.css        (CSS custom properties, focus, scrollbar)
 *   ops.gestalt  docs/design/design_specification_v1.md §5.1 (status semantics)
 * The contract itself is documented here: docs/ux/design-series.md.
 *
 * Still hand-written on purpose: no build step, no framework, no CSS preprocessor
 * (ADR-011 — a bundler for one stylesheet would be over-architecture).
