Adds an email allowlist (toggleable per deployment) that restricts
OAuth sign-in to listed emails while keeping read paths public.
Anonymous visitors now see the full app shell in read-only mode
instead of the §14.1 landing wall. Empty allowlist = gate off, so
deployments that don't enable it behave exactly as 0.2.3.
Also fixes single-finger scroll on /philosophy and other .chrome-pane
views on iOS Safari (.app: 100vh → 100dvh).
Renames deploy/nginx/rfc.wiggleverse.org.conf →
ohm.wiggleverse.org.conf to match the deployed-domain rename
(rfc.wiggleverse.org deprovisioned 2026-05-27).
See CHANGELOG.md for full details + upgrade steps.
