/*
 * WorkOnWeb Child — shared presentation stylesheet.
 *
 * Single source-of-truth for the WorkOnWeb design system. Authored from
 * DESIGN.md (the canonical visual spec); it is NOT a copy of
 * prototype/styles.css. Phase 9 Step 3A scope: design tokens + minimal global
 * base, button foundation, small shared utilities, and the responsive
 * container foundation. Page components (packages, browser mockups, FAQ,
 * header/footer, forms, case-study layouts) belong to their own steps.
 *
 * Tokens use a --wow- prefix to avoid collisions with Elementor/Hello globals.
 * Real @font-face and font preload are deferred to Step 3B (no font files yet).
