free tier note for Gemini, and credits note for Grok.

chat-widget.el: apostrophe in El native_js double-quoted strings caused
the El compiler to drop the backslash, producing broken JS single-quoted

main.el: /api/supabase-config was returning 403 for all stage Cloud Run
origins. Added marketing-stage-* prefix to the allowed list so the
checkout page can initialise Supabase during CI E2E runs.
