mara nit on #1: the three SVGs in static/ were identical copies
(md5 1108d7bd79ca…). Dropped favicon.svg + hex-mark.svg; kept
hyperhive.svg as the single source. Both consumers now point at
it: `<link rel="icon">` and the hero's `load_data(path="static/
hyperhive.svg", format="plain")`.
Also fixed: the original `load_data(path="hex-mark.svg")` would
have failed at build time anyway — Zola's `load_data` resolves
from project root, so files in `static/` need the full prefix
+ `format="plain"` to come back as raw markup. Build was never
validated locally (remote-builder unreachable from agent), so the
typo would have surfaced on the operator's first `nix build`.
Caught it during the dedupe pass.
If a future visual divergence is wanted (simpler favicon,
titled og:image), can split back into named copies then.
