v0.2.0:39 — Buy page: render tier card for single-public-policy products

Previously the tier picker gated on `policies.len() < 2` and returned
an empty string when a product had only one public policy. Buyers
saw just the price card + form — none of the entitlements, marketing
bullets, or description the operator had carefully authored on that
tier. Reported against the Recap product, which has 3 policies but
only Pro public; Pro's bullets were invisible to buyers.

Fixed:

- render_tier_picker gate flipped from `< 2` to `is_empty()`. A
  single public policy now renders a single tier card.
- New `.tiers-1` grid class: one centered column at ~480px max-width.
  Keeps the single card from stretching to the full 1040px container.
- `n` computation extends to handle 1 in the existing match arm.

The price card below the picker still renders unchanged for the
single-policy case — acts as the buy-confirmation summary. Operators
keeping most tiers private and only exposing one to buyers now get
the same rich tier-card render that multi-tier products always had.
