/**
 * `val-pattern`
 *
 * Componente de fondo geométrico inspirado en el sistema Valtech. Renderiza un
 * grid de tiles 100×100 con motifs (chevrons, triangles, diamonds, arrows) en
 * un SVG inline. Determinista vía `seed` o animado vía `reshuffle`.
 *
 * Cero dependencias externas — todo SVG.
 *
 * @example Como fondo de card (CSS absolute):
 * ```scss
 * .card { position: relative; overflow: hidden; }
 * .card val-pattern { position: absolute; inset: 0; z-index: 0; opacity: 0.4; }
 * .card .content { position: relative; z-index: 1; }
 * ```
 *
 * ```html
 * <div class="card">
 *   <val-pattern [props]="{ palette: 'purple', cols: 6, rows: 3, seed: 42 }" />
 *   <div class="content">Tu contenido aquí</div>
 * </div>
 * ```
 *
 * @example Como background animado (hero/login):
 * ```html
 * <val-pattern [props]="{ palette: 'lavender', cols: 16, rows: 8, animated: true }" />
 * ```
