/*
 * threats-v0.css — design-vote variant V0 of the /threats board (openspec/changes/
 * threat-board task 4.0b, frontend-design skill bake-off).
 *
 * Scope: every rule lives under .tv0-page so this file can never leak onto any other
 * page (the neutral board, v1, v2) — it is published next to threats-v1.css/
 * threats-v2.css and all three load only on their own /threats/design/v{n}/ route.
 *
 * Tokens: only --bg-primary/--bg-secondary/--bg-card/--border-color/--border-hover/
 * --text-primary/--text-secondary/--accent/--accent-hover/--warning/--error/--info
 * from style.css:3-40 (docs/DESIGN.md) are referenced here — no new hex color is
 * introduced anywhere in this file. Chart + chip colors are drawn from exactly five
 * of those tokens (accent, accent-hover, info, warning, error), the "max 6 hues"
 * budget this task sets, with text-secondary reserved for muted copy only (not used
 * as a data-ink color), shapes/radii/elevation follow docs/DESIGN.md's rule (flat
 * panels, 1px hairline, no box-shadow, the four named radius steps) — no
 * backdrop-filter, no drop-shadowed card.
 *
 * Idea: a mission-control console reading the same sensors the rest of the site
 * already renders as plain tables. HUD corner brackets on panels, a one-shot
 * staggered reveal on load, a scanning hairline across the hero, a live pulse next
 * to "time since last attack" — all CSS-only, all `transform`/`opacity`, all
 * dropped under prefers-reduced-motion.
