/*
 * pitchdeck.css — the investor deck (v4, 2026-10-16), rendered by src/site/deck.ts.
 *
 * Self-contained: the deck page loads only this sheet. Brand tokens are the
 * landing page's (ink #241F1F, accent #E95225, the blue-grey #9CB6C1), so the
 * deck reads as the same company. One claim per slide; type carries the page.
 * The one loud element is the benchmark matrix: accent = a bug flagged,
 * blue-grey = a false alarm on the fixed code, everything else stays quiet.
