/*
 * The FOI request builder.
 *
 * Structure from the foi-energy prototype — statutory ticker, four steps,
 * the letter live beside them on paper. Identity from the campaign: the
 * same deep navy ground, emerald and gold as the data pages, rather than
 * the prototype's lime on black. Whether this should instead be its own
 * sub-brand is CAC-20 and is still open.
 *
 * The paper panel is the one place a light surface is deliberate. A letter
 * is a letter; rendering it on dark glass would make it look like a
 * terminal, and the whole point is that the reader recognises the thing
 * they are about to print.
 *
 * Type floors as elsewhere in the campaign: 0.7rem for uppercase tracked
 * labels, 0.75rem for anything in sentence case.
