The site has flip-flopped on the snow effect every winter (add it,
remove it, repeat), meaning a PR round-trip each time. Instead, restore
the winter.js/is-land assets and gate them behind a new admin-toggleable
setting so the effect can be switched on/off from /admin/settings
without touching code.

Replace the single-icon popover with a dropdown of radio inputs with a
compact two-button toggle (light/dark), inspired by vale.rocks' design:
clicking an icon forces that theme, clicking the active icon again
returns to following the system preference. Keeps the existing
light-dark() colour-scheme mechanism and view-transition wipe
animation, and reuses the project's existing Fluent UI sun/moon icons.
