Free trial duration, expiry behavior, post-trial price explicit

A CTA labeled 'Start free trial' with no stated duration, post-trial price, or auto-conversion notice is textbook negative option marketing under FTC Negative Option Rule (2025) — the consumer is not making an informed decision to authorize future recurring charges. California ARL Section 17601 requires that all three facts (trial length, conversion trigger, post-trial price) appear at the point of enrollment. When a user discovers an unexpected $29 charge weeks after forgetting a trial, the result is a chargeback, not a cancellation — and Stripe's dispute rate threshold is 0.75%.

Display all three required trial disclosures — duration, auto-conversion, and post-trial price — at the trial entry point, not only at the Stripe checkout screen. In components/TrialCTA.tsx:

import { addDays, format } from 'date-fns'

const trialEndDate = format(addDays(new Date(), 14), 'MMMM d, yyyy')

<p className="trial-terms text-sm mt-2">
  Free for 14 days (until {trialEndDate}), then $29/month.
  Cancel before your trial ends and you won't be charged.
</p>

When credit card is collected at trial signup, make the conversion notice even more prominent: 'Your card will not be charged until [date]. Cancel before then to avoid the $29/month charge.' Ensure trial_period_days in stripe.subscriptions.create matches the number displayed.
