/* ============================================================================
 * ProvablySmart Tools — Editorial Forensic theme
 *
 * Direction: deep warm dark surface, editorial display serif (Fraunces),
 * gold accent used sparingly for emphasis, teal/coral for semantic states,
 * hairline borders, oversized monospace numerals for results, sharp 4-6px
 * radii. Inspired by financial / investigative-journalism interfaces.
 *
 * All class names + DOM structure preserved — JS keeps working unchanged.
