Move sign out below wiki button, tweak hover color, remove email
field label, rename 'Join Ghost Guild' to 'Pre-Register', and
remove 'Don't have an account?' text from login modal.
Hide 'Coming Soon' text when authenticated, change greeting to
'Welcome, Name' with inline underlined sign-out link, and force
Inter (font-sans) on all text.
Remove redundant checkMemberStatus() from coming-soon page since the
auth-init plugin already handles it. Add in-flight request deduplication
to prevent concurrent calls from any source. Strip debug console.logs.
Coming-soon page now shows a magic link login form for unauthenticated
visitors and a wiki link + sign out for logged-in members. The
coming-soon middleware allows /admin routes through (still protected by
admin middleware). A /login redirect page ensures invite email links work.
Remove auth bypass from coming-soon middleware so no one can access
the in-development site in production. Remove unused login button
from coming-soon page since wiki has its own OIDC login flow.
Add JWT-verified session check to coming-soon middleware so logged-in
members can access the full site. Add member login link and modal to
the coming-soon page so members can sign in before launch.
