WMBR — next
This is the parallel-deploy SPA we're building to replace the legacy multi-page site. The legacy site at www.whitemountainboard.com is unchanged and still serves all production traffic.
Auth state (server-validated)
You are not signed in. Sign in.
Scaffold note: auth here uses HTTP cookies via
@supabase/ssr. The session is set/read on the server before
the page reaches you, so the entire class of hydration-race / navigator.locks
/ duplicate-client bugs we've been patching in the legacy site doesn't
exist on this app by construction.
