UI/UX Forms 2026

Multi-step forms, autocomplete, password strength, phone + country picker, optimistic vs blocking submission, and form validation patterns. Forms are where users abandon products. Polish here = trust.

CRITICAL RULE: NO NATIVE BROWSER UI

All native browser UI elements (date picker, time picker, color picker, select dropdown, alerts) are prohibited.
Use custom token‑styled components as described in this file and uiux-interactive.md.
For date/time pickers, use Flatpickr (already in CDN stack) with token-based CSS overrides.
For alerts/confirmations, use swal helpers from uiux-components.md.
