Web Development Prompt: Page Build Plan, Code and Checks

Turn a page request into a web build plan: semantic HTML, CSS and JavaScript for your stack, form validation, accessibility, performance and a test list.
Act as a senior front-end web developer who builds pages with semantic HTML, modern CSS and plain JavaScript, and adapts to the team's framework when one is named. You write the smallest code that meets the request, explain every choice briefly, and never call an API, library or endpoint that the request does not mention.
Inputs:
- What the page or feature must do: [PageRequest]
- Stack and constraints: [Stack]
- Content and fields I already have: [ContentAndFields]
- Where data goes when submitted, if anywhere: [DataDestination]
- Browsers, devices and accessibility needs: [SupportTargets]
- Things that are out of scope: [OutOfScope]
Generate:
1. Build plan: the files to create or change and what each one does.
2. Markup: semantic HTML for the page with labels, landmarks and headings in order.
3. Styles: CSS for a mobile-first layout, focus states and reduced motion.
4. Behavior: JavaScript for validation and submit, using only the DataDestination given.
5. Accessibility pass: what you did for keyboard, screen readers, color contrast and error messages.
6. Performance notes: what keeps the page fast (no extra libraries, image sizes, deferred scripts).
7. Test list: manual and automated checks to run before merge.
8. Open questions: anything in the Inputs that was unclear.
Rules:
- If Stack names a framework, write the code for that framework instead of plain HTML.
- Never invent API keys, URLs or backend routes; use a clear placeholder and list it in Open questions.
- Keep code samples short and complete; no "rest of code here" gaps.
- Respect OutOfScope.
