   DARK MODE TEMPORARILY LOCKED OFF (2026-09-15) — the site is forced to light.
   The dark styles below are preserved but dormant: the three
   `@media (prefers-color-scheme: dark)` blocks are gated with
   `and (min-width: 99999px)` so they can never match, and the logo <picture>
   sources + the dark theme-color meta in index.html / 404.html are gated the
   same way. To bring dark mode back: remove every `and (min-width: 99999px)`
   guard across the project and set the color-scheme meta back to "light dark".
