/* The platform administration: a back office, and it looks like one.
 *
 * The product is a bright, friendly application a club treasurer uses a
 * few evenings a month. This is not that. This is the desk the service is
 * run from — a ledger, an account statement, a stack of invoices — and it
 * is built out of that world: ink for the rail, paper for the surface,
 * hairlines instead of cards, and one deep petrol that marks everything
 * that can be acted on.
 *
 * The one rule the whole thing hangs on: **identifiers are machine, names
 * are human.** Every slug, invoice number, IBAN, reference and amount is
 * set in the monospace face with tabular figures; every name, title and
 * sentence is set in the sans. It is the reason a column of numbers here
 * lines up and a column of names does not have to.
 *
 * Loaded on top of Tabler (conjunto/base.html brings it), so selectors are
 * prefixed `bo-` and specific enough to win without !important.
