   THE HOUSE ANIMATION
   One entrance, used everywhere: fade + rise, ~420ms, once, no reverse.

   Safety contract (this is deliberate, do not "simplify" it):
   the opacity:0 rule is gated behind .js on <html>, which an inline script in
   the <head> sets before first paint. If scripting is off, main.js 404s, or a
   JS error fires, no element is ever hidden — the page just renders static.
   Reveals are driven by getBoundingClientRect in a throttled scroll handler,
   NOT IntersectionObserver, and main.js carries a failsafe that reveals
   everything if nothing has revealed after a few seconds.
