/* beforeyoutask -- forensic clean-room design system.
   No build step. Monospace = the instrument (wordmark, labels, paths, data);
   sans = the plain-language explanation. One teal instrument accent; muted,
   non-neon severity colours reserved for verdicts. Light + dark via tokens.
   The SSE result fragments' class hooks (.results, .finding-group,
   .coverage-row, .inventory-panel, .limitations, ...) are all styled here. */
