/* pricing.css — ON1 /pricing canonical aggregator
 *
 * Aesthetic flavor: MENU-CARD-BISTRO (36th distinct surface).
 *
 * Mental image: a French bistro's à-la-carte menu card. Cream
 * menu-paper background with a barely-warm tan tint, hand-bound
 * frame at the page edge, copperplate-script "track" names, ruled
 * price columns with dotted leader-lines connecting product names
 * to prices in a thin column on the right. Section dividers are
 * ornament-flanked thin rules ("§"). Body lines in Familjen Grotesk
 * for body, IBM Plex Mono for prices, Chakra Petch for the
 * masthead. Chalkboard-green ink accent for the "subscribe" CTA.
 *
 * Distinct from:
 *   - 27th (monospace-quote-sheet, nrs-api-pricing.css): typewriter
 *     carbon-copy, single-product quote-sheet, dot-matrix forms.
 *   - 35th (gazette-broadsheet, e.g. regulator-updates): newspaper
 *     column-grid, drop caps, ALL-CAPS section heads.
 *   - 30th (invoice-deluxe-watermark, tender-csv-tier-upgrade): cream
 *     ledger with gold-leaf foil + ruled tax-form comparison ledger.
 * Bistro card differs because it's an EXECUTIVE MENU — multiple
 * product groups read side-by-side as one CARTE, dotted lead-lines
 * tie name to price like in a real menu, not single-product invoice.
 *
 * No innerHTML in companion JS; this file is the visual contract only.
