Activation mail is Apex-branded

Crew invites on this board preview mail from Apex Concrete Finishes — the circular seal, copper, and this company name. They do not go out as Finish at Last Co. Member login is not wired on the sample board, so this page does not consume a token against Hayden's memberships.

Open crew invites

Paste supabase/templates/confirm-signup-apex.html into a separate Apex Auth project with Site URL https://apex.carson.systems. Never onto the Finish at Last Co. project.
