Generate a branded, single-file HTML client intake questionnaire for any service business. Picks the right question set (brand identity, web design, automation project, or pre-call brief), styles it with the project's brand colours and fonts, and includes validation, progress, and a success state. Pairs with php-form-mailer to make it send email. Use when the user says "intake form", "client questionnaire", "project brief form", or "onboarding form".
