/*
 * Temperature Zero — Landing Modules
 *
 * Module styles for the seven landing-page partials. Inherits design
 * tokens from style.css :root (--tz-bg, --tz-accent, --tz-mono, etc.).
 *
 * Versioned filename: bypasses Cloudflare's ?ver= cache normalization.
 * Bump the filename (landing-modules.1.3.css) when shipping changes.
 *
 * 1.0 — initial Prompt 2 module styles
 * 1.1 — Prompt 3: .tz-freshness, lifted .tz-sf-*
 * 1.2 — Prompt 4: .tz-matrix (benchmark matrix; legacy .tz-leaderboard
 *        styles kept below the matrix block for safety until confirmed unused)
 * 1.3 — Prompt 5: .tz-spotlight (briefing-spotlight module; "Today in AI"
 *        slot repointed from counter tiles to latest-briefing themes).
 *        Counter subsystem retired same arc; .tz-counter styles removed.
