/* "Ledger" Theme — a bookkeeper's account book.
 *
 * Clean is this site's editorial era — a magazine page. This is the other
 * document that the index's audits, budgets, and mineral-summary trackers
 * actually produce: a ruled ledger sheet, two pens deep — blue ink for what
 * was entered, a red stamp for what was checked.
 *
 * Costs nothing to ship: Inter and JetBrains Mono are both already in the
 * base font request (JetBrains Mono carries headings here instead of body
 * text), and the ledger's ruled lines are a CSS gradient — no image asset.
 *
 * Contrast: ink on sheet is 16.1:1. --stamp (6.0:1), --entry (8.7:1) and
 * --muted (6.4:1) all clear AA at body size with real margin. --stamp-light
 * is decorative only (hover borders, the status dot, the reading-progress
 * bar) and is never used for text.
 *
 * Every rule is scoped under `body.theme-ledger`.
