- auto_charge: verify payment_intent.status is succeeded/processing before returning success; add description/metadata params so subscription charges are labeled correctly in Stripe
- pricing: redirect to ?success= after upgrade/downgrade so the persistent server-side banner shows instead of a 1.5s toast that disappears on reload
- pricing GET endpoint: pass success/error query params to template context
- base modal: support html:true option in open() so showConfirm can render HTML content; update showConfirm signature to accept html flag
- pricing: pass html=true to showConfirm so the upgrade confirmation renders bold/colored text instead of raw tags
