/*
 * IDD — componenti form
 * ----------------------------------------------------------------
 * Stili per input, select, textarea, checkbox, radio, file upload e
 * bottoni di invio, coerenti con la palette e i pattern già usati nel
 * tema (header.php, newsletter.php): colori da tailwind.config in
 * functions.php (idd_tailwind_config), font Hanken Grotesk.
 *
 * Sono classi CSS "normali" (non utility Tailwind) perché Tailwind è
 * caricato via Play CDN: legge le classi già presenti nell'HTML ma
 * non compila @apply dentro questo file. Vanno quindi usate così
 * come sono, eventualmente insieme a classi Tailwind di layout
 * (grid, gap, ecc.) sullo stesso markup.
 *
 * Markup di riferimento: vedi idd-form-guide.php nella stessa cartella.
