 * whole surface "reads as one product" (AGENTS.md SS6 aesthetics rule).
 * HOW: Loaded after theme.css; references --brand-primary/--brand-ink/
 * --brand-accent exclusively — no literal hex codes below. State (pending/
 * running/done/error/skipped) is distinguished by border style, icon
 * glyph, and text label together, never by color alone (WCAG "use of
 * color" success criterion, frontend/README.md accessibility note).
