/*
 * WCAG 2.2 AA Compliance — enforced at the template level.
 * All campaigns served by this system inherit these standards automatically.
 * When standards update, update this file and all campaigns benefit immediately.
 *
 * Criteria addressed:
 *   1.1.1  Non-text content — alt text on hero image (set in intake Step 2)
 *   1.3.1  Info and relationships — semantic HTML, fieldsets, legends
 *   1.3.5  Input purpose — autocomplete attributes on all form fields
 *   1.4.3  Contrast — 4.5:1 minimum for text; button text chosen via WCAG luminance formula
 *   1.4.4  Resize text — rem/em units throughout; layout reflows at 320px
 *   1.4.10 Reflow — single-column at 320px, no horizontal scroll
 *   1.4.11 Non-text contrast — UI components (inputs, buttons) meet 3:1 against background
 *   1.4.12 Text spacing — no fixed heights that clip text when spacing is increased
 *   2.1.1  Keyboard — all controls reachable and operable by keyboard
 *   2.4.1  Bypass blocks — skip-to-main link
 *   2.4.2  Page titled — title set from config.productName
 *   2.4.3  Focus order — logical DOM order matches visual order
 *   2.4.7  Focus visible — visible focus ring on all interactive elements
 *   2.4.11 Focus not obscured — no sticky elements covering focused items
 *   2.5.3  Label in name — visible labels match accessible names
 *   2.5.8  Target size — interactive elements min 44×44px
 *   3.1.1  Language — lang attribute set from campaign language config
 *   3.3.1  Error identification — errors described in text, not colour alone
 *   3.3.2  Labels or instructions — all inputs have visible labels
 *   4.1.3  Status messages — success/error use aria-live regions
