Share images: the master mark replaces the ringed coin on every og image; og.png (was a 404) added; ?v=2 cache bust

Browse source 
make-icons.py make_social(): og-small.png (256 square, the compact card index/live/litepaper declare), og-square.png
(1024), og-coin.png and og.png (1200x630: mark left, IGNEUM wordmark, tagline, subline; same layout as before, no ring,
no glow). bench.html, evidence.html and build.mjs referenced /og.png, which did not exist; they now get the 1200x630 card
with width/height 1200x630 and twitter:card summary_large_image. Every og:image and twitter:image carries ?v=2 so
Slack, X and iMessage refetch. brand/profile: github-social-1280x640.png (repository social preview) and
vercel-avatar-512.png. bench.html edited by hand for the meta only (a build.mjs run would publish uncommitted log entries).

Inline SVG favicons (the `data:` link in every page head) carry the same square and mark, so a page shows the right icon
before the `.ico` loads.
## Not regenerated
- `site/og-small.png`, `og-square.png`, `og-coin.png`: the social card design, left as it was by instruction (4 October 2026).
- `brand/igneum-coin-1024.png`: the old ringed coin. Retired as a source; nothing reads it now.
- `brand/igneum-mark-transparent-1024.png`, the wordmark PNGs and `Unbounded.ttf`: unchanged.
