/* States — empty / loading / error
 * Source: docs/superpowers/plans/2026-04-18-app-polish-maximization.md Theme 3A
 * Tokens: web/static/css/_tokens.css
 *
 * Three reusable display states:
 *   .state--empty   : zero-data surface (designed, not bare <p>)
 *   .state--loading : async work in flight (spinner + label)
 *   .state--error   : recoverable failure (alert icon + recovery action)
 *
 * Macros: empty_state(), loading_state(), error_state() in _macros.html.
