/* Sway's website. Lamplit Toy (docs/STYLE_GUIDE.md): night outside, lamplight inside.
   The harbour, the two sea bands and the footer are always night. The sections between are lamplit paper
   (in dark mode the lamp is turned low: deep blue paper, cream words). Letters, postcards and photo frames
   are things you could hold, so they stay cream in both.
   Everything is Sway's own art (img/, made by tools/SwayArt/make_site_art.py). No outside requests.
   Motion: the harbour builds up once as the page opens; idle motion runs only with site.js, only while its
   section is on the screen, stops with the pause button, and never runs with "reduce motion". */
