/* ==========================================================================
   ACTIVE SEASONAL THEME
   --------------------------------------------------------------------------
   This file decides the site's seasonal look. Every page loads it AFTER
   site.css, so whatever is in here overrides the year-round colours — and
   nothing else. Layout, text and structure never change.

   EMPTY (as it is now)  = the normal year-round look: blood red on black.

   To TURN ON a theme:  copy the entire contents of
       css/theme-halloween.css   or   css/theme-christmas.css
   into this file (replacing everything), then rebuild + deploy.

   To TURN IT OFF:  empty this file again (leave just this comment), rebuild
   + deploy.

   Only the optics change. The shop, the gallery, the wording — all untouched.

   NOTE: Halloween is currently on a SCHEDULE, not this slot. A tiny script in
   every page's <head> loads css/theme-halloween.css automatically while the
   date is before 2026-11-01, then stops (site returns to normal on its own).
   To change that window, edit the Date.UTC(...) in build.py's _head() and in
   the four hand-authored pages (index + the three style pages), then rebuild.
   This slot stays free for any manual/one-off theme.
