/* =====================================================================
 * setup-brand.css — nanocosmos Product Theme (dark), applied to the
 * chroma-key workbench UI.
 *
 * Tier:   Product page (web.pages.gitlab.nanocosmos.cloud)
 * Fonts:  Lexend Deca (heading/buttons) + Source Sans 3 (body) — both
 *         self-hosted from https://www.nanocosmos.net/fonts/ via
 *         fonts.css, loaded before this file. No Google Fonts.
 *         Monospace stays a system stack (ui-monospace/SFMono/Menlo/
 *         Consolas) — Roboto Mono is not currently self-hosted anywhere
 *         in this repo, and this redesign does not reintroduce Google
 *         Fonts just to get it. Flagging, not silently deciding: see
 *         nanocosmos-brand-guidelines' own "Font-hosting note" for the
 *         open item on self-hosting Lexend Deca/Source Sans Pro/Roboto
 *         Mono centrally — Roboto Mono should move to the same
 *         self-hosted path once that's resolved.
 *
 * Tokens: canonical nanocosmos Product Theme tokens (--accent-orange
 *         #e5883c / --accent-blue #408bc3 / --bg #0d171e / --panel
 *         #252a2f / --panel-inset #1c2228 / --border #2e343d) — see
 *         nanocosmos-brand-guidelines/product-theme.css. This is a
 *         DIFFERENT accent pair from the marketing site (#F48220 /
 *         #0F8DC8) — do not mix them back in.
 *
 * No green/red/yellow anywhere (status colors are bucketed into the two
 * brand accents only — orange = attention: error/warning/live, blue =
 * positive: success/done — icons and labels carry the specific
 * meaning). The one deliberate exception: the chroma-key color swatches
 * (#00FF00 green-screen / #0057FF blue-screen presets) and the RGB
 * channel slider thumbs — those literal colors ARE the data (what pixel
 * color is being keyed / previewed), not a status indicator, so they
 * stay real red/green/blue.
 *
 * Flat surfaces, no drop-shadow, no gradients (except the mandatory
 * header gradient bar) — panels are a plain fill + 1px border. Buttons,
 * pills, chips, badges, and toggles are all full-pill (999px). Panels
 * are a modest 4px. Ordinary inputs/selects are 8px with a uniform
 * border on every side — no colored accent stripe on any edge, ever
 * (the previous `border-left: 3px solid var(--orange)` on every input
 * was exactly that anti-pattern; removed throughout).
 *
 * Built from scratch — no rules borrowed from styles.css. Only the
 * layout primitives (workbench grid, upload grid, sections, sticky
 * preview, sliders + value-input shape, combo boxes, stream cards) are
 * preserved by intent — this is a re-skin, not a re-architecture.
