+- Single row: brand lockup → tagline → icon-only social buttons pushed right; then a divider and a bottom bar (copyright left, Privacy / Cookie / Contact / `hello@erigon.tech` right).
+- No link columns and no postal address. Those belong to the **full** footer, which is erigon.tech's, not a docs site's. Do not "fix" this footer by porting them back.
+- Nunito Sans throughout, with the `erigon.tech` wordmark in Quantify 700.
+- Every interactive element hovers Erigon Orange `#EF7716`.
+- Theme-aware surface via `--footer-*` custom properties in `src/css/custom.css`: white in light mode, black in dark. It is **not** always black — that was the previous five-column footer.
+- Both modes carry a 1px top edge. In light because a white footer on a white body has no edge of its own; in dark because `#000000` against the `#0A0A0A` page body is imperceptible.
+- Fine print is 0.55 alpha, deliberately not a mirrored 0.35: equal alpha is not equal perceived contrast across inverted surfaces, and 0.35 on white computes to 2.44:1, failing WCAG AA.
