11// Renderer turns a Program into the three markdown pages a grant program
12// needs: the board, one request, and the ledger. Everything that differs
13// between one program and the next is a field, so a realm's whole Render is
14// building this literal and calling it.
15//
16// Build it INSIDE Render rather than storing it in a realm global: Note is a
17// func, and Balance has to be read fresh on every call anyway.
18//
19// # Escaping
20//
21// Everything a caller typed (titles, bodies, reasons, proofs, notes) is
22// escaped here, once, through p/moul/kit/ui and p/nt/markdown/sanitize. A
23// realm does not repeat it and must not pre-escape: escaping twice shows the
24// backslashes. The realm's OWN fields below (Title, Intro, Notes, Footer) are
25// chrome, are written by whoever deployed the realm, and are emitted as-is so
26// they can carry markdown.
