/*
 * SmartInventory web — custom auth (login + register) stylesheet.
 *
 * Source: docs/reference/new-design/login/design_handoff_smart_inventory_login/
 *         web-app-login.html (May 2026 handoff). The bundle's :root token block
 *         is intentionally NOT duplicated here; design-tokens.css is the single
 *         source of truth (imported below, mirrors the subpage-shared.css
 *         pattern).
 *
 * Namespace: every top-level component class has been prefixed with `.login-*`
 * to avoid silent cascade collisions with the short selectors landing.css
 * declares in the global namespace (`.section`, `.eyebrow`, etc.). See
 * web/CLAUDE.md § "Landing-specific assets" for the warning.
 *
 * The body-class toggle `body.mode-login` / `body.mode-register` stays
 * un-prefixed — it is a state class, not a component, and is referenced from
 * web/public/web/js/index.js.
 *
 * Tracking: GitHub issue #842 (under umbrella #838).
