anti 5a34b1846c fix(decnet_web/Layout): kill residual theme-swap open flash
Even with fill: 'both', the new pseudo paints once at its default
style (no clip-path = full size) before the JS animation
registers — the brief open flash that survived the previous fix.

Pre-publish click coords as --reveal-x / --reveal-y on <html>
before calling startViewTransition. The static CSS rule on
::view-transition-new(root) now sets clip-path: circle(0px at
var(--reveal-x) var(--reveal-y)) as the pseudo's default, so
the very first paint is already fully clipped. The animation
then grows the circle outward from there.
