/*
 * INTAKE FORM STYLES
 * File: assets/css/intake.css
 *
 * WHAT THIS FILE DOES:
 *   Controls the look of the sign-up form where a prospect types in their company name,
 *   website, and email — including all the interactive bits like the autocomplete dropdown
 *   and the spinning submit button.
 *
 * USED BY:
 *   index.html (the first page a prospect sees)
 *
 * SECTIONS INSIDE:
 *   - Company name input and autocomplete dropdown
 *   - Candidate company cards (logo thumbnails shown during company selection)
 *   - Confirmation state (green checkmark after a company is chosen)
 *   - Form validation error messages
 *   - Submit button (normal, loading, and disabled states)
 *   - Language toggle pill (English / Thai switcher)
