/*
 * tender-csv-tier-upgrade.css — 30th distinct flavor: invoice-deluxe-watermark.
 *
 * Visual language: premium ledger paper (cream + faint grid), ink-blue
 * ruled lines, gold-leaf "TIER" header watermark + foil stamp, hand-
 * typed amounts in tabular monospace, classifieds-style price columns.
 *
 * Body: Familjen Grotesk. Headlines + house mark: Chakra Petch.
 * Ledger amounts + technical labels: IBM Plex Mono with tabular figures.
 *
 * Contrast: ink #1e2a3a + ink-mute #4c5b6e on cream #f5efe0 reads 9-13:1
 * (AAA on body text). Gold #a87526 is decorative only (never solely
 * load-bearing).
