/*
 * WhatsApp Cloud Engine — auth pages (sign in / sign up / forgot password).
 * Hand-written CSS, deliberately separate from techmits_ruby's compiled
 * Tailwind bundle and from the blog's stylesheet — see CLAUDE.md
 * "UI & Branding: keep this engine's assets separate". Colors match the
 * main site's documented WCAG-AA palette (see techmits_ruby's CLAUDE.md
 * "Color standards") so this still *looks* like the same product.
