/* Sleep Station — the landing page.
   One idea: a night, told slowly. A moon, one sentence, then the night itself as you scroll.
   Nothing here decorates; every element is either the story or the way in.

   Robustness rule: the page is complete with no JavaScript and no animation. The default
   state is the finished, still page. `html.js` (set by site.js) turns the night into the
   scroll-driven scene; `html.anim` (set only when the visitor has not asked for reduced
   motion) adds the autonomous motion — entrances, the breathing moon, drifting stars. */
