plan: intake to plan by a model; doors, labelled groups, the whole card

Work from another session, committed as found (tests green):

- `plan` reads an intake into a plan.yaml (a model decides needs,
  stages, forms and budgets; a person reads the result before build).
- Plans gain `doors` (a first question before the forms, when a front
  door would carry more than five needs), `groups` with labels that a
  select may draw its options from (`options_from: groups`), `private`
  fields kept off public pages, `multiple` selects, and `max_fields`
  as what the intake said the person will tolerate.
- `card.rs`: an alternative as the visitor meets it, in text, so the
  answering visitor and `rate` read the served card, not the heading.
- `rate` reads followup pages from the repo and reports "what happens
  next" as not measured rather than zero when it cannot.

+what_we_do: >
+  Six physiotherapists and a receptionist. People come to us with
+  pain, injuries and after operations; we assess them and treat them
+  over a course of sessions. Some come on their own, some are sent by
+  a GP or a hospital, and some have insurance that pays if the insurer
+  approves the course first.
+
+who_comes_to_us: >
+  People with something that hurts who want to see the right
+  therapist. Patients who already have a time and need to move or
+  drop it. GPs and hospital wards sending us someone, who want to
+  hear how it went. Insurers, through us, when a course has to be
+  approved before it starts.
+
+what_we_keep_track_of: >
+  Requests for a first appointment: they come in, we offer a time with
+  a therapist who suits, and it is either booked or they go elsewhere.
+  Cancellations: someone can't come; we either find them a new time or
+  give the slot to someone waiting.
+  Referrals: a doctor sends someone, we accept it, book them in, treat
+  them, and send the doctor a report at the end. Sometimes we send it
+  back because it isn't something we treat.
+  Insurance approvals: for some patients we have to ask the insurer
+  before we start; we send the request and it comes back approved or
+  refused.
+  No-shows: someone doesn't turn up and doesn't call. The receptionist
+  rings them and either rebooks or, after a couple of times, closes it.
+
+who_is_involved: >
+  The receptionist handles every request, cancellation, referral and
+  approval. The therapists treat and write the report back to the
+  doctor, and they are the ones who notice a no-show.
+
+what_slows_us_down: >
+  Referrals, cancellations and insurance approvals all go through one
+  inbox that only the receptionist understands. Therapists tell her
+  about no-shows in the corridor and they get forgotten.
