/*
 * site.css -- the ROOT.war design system (PLAN-3 S7.1).
 *
 * No framework, no build step, no JavaScript: one file, custom properties for the palette,
 * mobile first, and a budget of 30 KB that tools/site/run-design-check.ps1 enforces.
 *
 * Palette: navy for the hero and the footer, a light blue-grey page, one blue for links and
 * controls, gold for the primary call to action. Marketing pages are meant to look LIGHTER
 * than the application -- nothing here imitates SmartClient chrome.
 *
 * Contrast: every foreground/background pair below is checked against WCAG 2.1 AA by
 * DesignCheck (4.5:1 for body text, 3:1 for large text and UI edges). Two consequences that
 * are easy to undo by accident:
 *   - gold carries NAVY text, never white (white on #d4a017 is 2.4:1);
 *   - --blue is the lightest blue allowed on white (5.3:1); hover goes darker, not lighter.
 *
 * Order: tokens, base, layout, header, footer, components, buttons, then the public
 * pages built in S2.2 - S6.5 (forms, data primitives, pricing, checkout, account), then
 * print. The /admin/* back office is assets/css/admin.css -- it is a third of the bytes
 * and no visitor ever loads it, which is how this file stays inside its budget.
