The tab logo and social preview were still on the old teal palette. Retone both
to the electric cyan→magenta theme matching the hero nameplate:
- favicon.svg: jw monogram + prompt-line + cursor on a cyan→magenta gradient.
- og.png (gen-og.mjs): name in the cyan→violet→magenta hero gradient, cyan
eyebrow/separators, magenta URL, cyan→magenta top bar + dual corner glows.
- bump ?v=2 on both refs (public/ assets are CF-edge-cached + social platforms
cache OG hard) so the new art shows immediately.
