/* Rooms of the world (16 Oct 2026, the owner: "внутренние страницы уже без эффекта такого как у нас воздушности и плоские").
   Every inner page stands in one place of the homepage's world: the same pre-rendered stills as the airy level
   (images/space-stills), two to four per page, handed over as the page scrolls (js/space-room.js) with a slow push-in,
   so reading a page is a short flight through its part of the world. A veil in the theme's own paper keeps the copy's

/* ---- light and colour over the live world (17 Oct, second pass) ---------------------------------------------------
   The owner: «настроить цвета, графику, а то были странные свечения, засветы». Three causes, all here:

   1. The veil. It was written for the *stills*, which are flat renders that need dimming for white copy. The live
      world dims itself from the camera's own position (js/space-dim.js), so the same veil on top of it was a second
      dimming — and on the light theme a 70–78 % white sheet over a moving frame reads as a wash, a flat glare rather
      than air. PLAN-LIVE-ROOMS.md said the veil should be "lighter when live"; this is that rule, finally applied.
   2. The cursor light (.cursor-light, css/portfolio-v42.css) is a 560 px radial blob set to mix-blend-mode:screen on
      the dark theme. Screen only ever brightens: over a dark page it is a soft sheen, but over the lit world it is a
      moving bright patch that follows the pointer — the "странное свечение". It belongs to the flat pages.
   3. The page grain and the old page field are already off; nothing else may add light on top of the world. */
