/*
 * Training store: cart, checkout, success (docs/plans/marketing-site-phase-3.md, slice S5), plus the buying pieces on
 * the hub and the course pages (docs/plans/website-conversion-plan.md, Phase A / A5: seat picker, whole-district
 * preset, phone Add bar). Loaded as /site/store.css?v=N after /site/site.css on the store pages, the hub and the three
 * course pages. Same tokens as site.css; no new colours. The store-page rules are scoped under main.store, because
 * the store scripts build markup with generic class names (.panel, .line, .summary, .amt …) that must not leak into,
 * or pick up rules from, the rest of the site; the hub/course rules use their own class names (end of the file).
 * The class names are a contract with the inline store scripts (§6 of the plan; tested in site-routes.test.js).
 * Money: mono stack, tabular figures, right-aligned, two decimals (the scripts format the figures).
