/* ── Damiano Giusti — blog & cv theme ─────────────────────────
   Monospace, minimal. Light by default, follows OS, toggle on top.
   Neutral palette + warm amber accent. Post images bring colour.
   A few quiet nods to guitar / playing live.
   All text pairs verified WCAG AA (>=4.5:1) in both themes. */
