/*
 * AI summary block — shared visual treatment for every Phase 4 surface.
 *
 * Lives inside tool result regions (between score and metrics, after
 * the headline). Distinct accent panel so users perceive AI output as
 * "explanatory" rather than "definitive data".
 *
 * Variants:
 *   .ai-summary--loading — spinner + label while fetching
 *   .ai-summary--ready   — header (icon + title + provider badge) + body
 *   .ai-summary--quota   — soft paywall nudge
 *   .ai-summary           hidden by default until JS unhides
 *
 * Plus the EN-only consent modal (.ai-consent-modal *).
