/* Netquirk site standard — site-v2.css
 *
 * Single hand-written stylesheet for the public apex. No framework, no
 * @import, no external URLs, no web fonts, no build step. Mirrors the
 * design system documented in
 * .claude/skills/netquirk-website-quality/site-standard.md (the vmgenie
 * standard), retuned for netquirk.com.
 *
 * Tokens on :root. Components: layout, hero, buttons, cards, browser
 * frame for product screenshots, projects grid, shared page shell
 * (header with logo / nav / sign-in / CTA, three-column footer with
 * legal line), main.prose for content pages. AA contrast, visible
 * focus rings, [hidden] wins, grids use minmax(0, 1fr).
 *
 * The bare word for the input attribute is intentionally absent from
 * this stylesheet — even in CSS comments and pseudo-element selectors
 * — because the banned-phrase scanner would flag it. Form fields do
 * not use that visual treatment; the descriptive text is rendered
 * alongside the field instead.
