/*
 * The one stylesheet of BetaStore: plain type, one narrow column, the footer.
 *
 * Project: beta-store — partner storefront for New York Groupon experience deals (Partner Storefront API)
 * Module:  public/style.css
 * Deps:    none (served from public/ by [assets] in wrangler.toml)
 * Tested:  n/a (tests/integration/pages/public-pages.test.ts checks that every page links it)
 *
 * Key responsibilities:
 * - Type, spacing and colours of every page
 * - The listing cards, the deal page options and gallery, the cart lines, notices, total and Buy now
 *
 * Design constraints:
 * - Plain CSS: no framework, no web font, no remote url(); the CSP allows style-src 'self' only
 * - Our own colours; no Groupon colours or marks (spec §3.4)
