{{/* abono-paywall — what stands where locked content would be: why it
     is locked, and the way in. A reader who is not signed in is asked to
     sign in (they cannot buy as no one); a signed-in reader sees the
     plans, or a link to them.

     The block is a padded box when it holds only words and a button; with
     the picker inline the plan boxes are the boxes, and it is a plain section.

     Keys:
       Offers     []abono.Offer, required — from Service.Offers
       SignedIn   bool, required
       SigninURL  string — where "sign in" goes; used when not SignedIn
       Action     string — where the buy forms post; used when SignedIn
       PlansURL   string, optional — when set, a signed-in reader gets a
                  "see plans" link there instead of the picker inline
