Zone 6 Fitness — Join a class

This paragraph is the pretend gym website. Everything below the line is fpt-book.js — the single-script embed a gym pastes on their own site (Slice 3 / Feature #30015).

This is the REAL production embed snippet (dev enclave): the script is served by the enclave and derives its own origin, and with no data-brand attribute it wears the gym's saved Branding colors automatically — same source of truth as the hosted booking page.
