 * Server-rendered shell with the first snapshot fetched directly from

 * Detectives:
 *   - hypothesis_tournament → Sherlock Holmes
 *   - evidence_chain → Edmond Locard
 *
 * Renders:
 *   - Phase tracker (queued → claimed → running → complete | failed)
 *   - Hypothesis cards w/ prior+posterior bars + Tetlock confidence_band badge
 *   - Evidence cards w/ grade A/B/C badge + verbatim_excerpt + bbox crop link
