memory: the SVOS concept round is with the operator, and a latent CSS defect it surfaced

Three rulings open on booth-svos-retheme (ship / voice / emblem). The branch is
an inert ref; merge is gated on the rulings. Verified independently: nothing
checked out, main clean, merge-tree clean, merged tree 649 green.

The fixup hold is now partial — booth.html is released because design-dev does
not touch it, so bug-hunt findings there land immediately.

And a real one he caught on our side: base.html reads four CSS custom properties
and defines none of them, 15 uses without a fallback. An undefined var makes the
whole declaration invalid at computed-value time, so those buttons have had no
border at all and a transparent background — not merely default colours. The U7
rail reads the same names with fallbacks, which is why the rail looked
deliberate and the buttons under it never did. Assigned to his rewrite; fixing
it on main would collide with the one file he is rewriting.
