zeekay ed8e3b3d50 the favicon was a blank white square ...

Not a metaphor: every pixel of the 32x32 this site served was 255,255,255. I had
compared it to the repo by checksum earlier, found them equal, and called it
fixed — which is exactly how a blank icon survives. Bytes match, and nothing is
drawn.

Three sibling surfaces had the opposite version of the same fault: hanzo.ai,
cloud.hanzo.ai and sentry.hanzo.ai served a 48x48 whose 2,304 pixels were all
black.

The cause was upstream of both, in @hanzo/logo's getFaviconSVG: a black tile with
a white mark. A tab strip is light in every default theme, so that reads as a
blob, and the transparent variant beside it vanishes. Fixed there (v1.0.15,
pushed) and taken from that build here, rather than drawn again locally — one
source, so the estate converges instead of each surface inventing a mark.

Black mark, white ground, at every size the browser might ask for. The tile
carries its own contrast, so it holds on light and dark chrome. favicon-dev keeps
the old polarity on purpose: a dev tab should not look identical to production.
safari-pinned-tab.svg is untouched — it is a mask, and a mask wants a silhouette,
not a ground.

Verified per size, not per hash: every PNG and all six ICO frames read white at
the edge and black at the centre. The ?v= tag moves so browsers refetch instead
of showing the blank one from cache.
