Two follow-ups to patch2 (both in patch-compat-sfe.py, guarded):
1. compat_needs_sfe() now also serves the SFE to ANY iOS browser on iOS<=16.3,
not just Safari. iOS Chrome/Firefox are WebKit skins (Apple mandate) reporting
a non-Safari UA family, so the Safari-only check missed them and they still got
the blank modern SPA. Added an os.family=="iOS" + version<=16.3 branch.
2. Inject static social-login <a> links (Continue with Google/GitHub/Facebook ->
/source/oauth/login/<slug>/) into the SFE shell (flow-sfe.html). The SFE
architecturally can't render Identification-stage sources (authentik docs), and
emo's account (emil.barzin@gmail.com) is Google-only with NO password — so the
SFE's username/password form was a dead end. The links are plain redirects that
work on any browser. Slugs are static; re-verify on source changes.
Tag -> 2026.2.4-patch3; values repoint + docs land once GHA builds it.
