/* Smart Coop Door — "day arc", 2026-10-03.

   The page lives one full day: dawn hero, morning architecture, midday
   control, an afternoon schedule that follows the sun, golden-hour outdoor
   engineering, one night chapter, and a field-notes ledger read over the
   next morning's coffee before the waitlist opens into a second dawn.

   Colour lives in product-theme.css (day defaults, .night-chapter overrides);
   this file holds layout, type and light placement only. */
