/* w3p-forensic — the "reveal" dialect layered on forge-dark.
 *
 * Registers of the language:
 *   - surface: near-black green-ink; the page reads like a case file.
 *   - green (#00E664) is the reveal light — used ONLY for evidence, the
 *     scanline, and actions. It never decorates.
 *   - JetBrains Mono carries forensic metadata (evidence refs, dates,
 *     confidence, status). Inter carries prose.
 *   - hairlines + quiet grid instead of cards wherever possible.
