CODING AGENTS: READ THIS FIRST

This is a handoff bundle from Claude Design (claude.ai/design).

A user mocked up designs in HTML/CSS/JS using an AI design tool, then exported this bundle so a coding agent can implement the designs for real.

What you should do — IMPORTANT

Read the chat transcripts first. There are 31 chat transcript(s) in chats/. The transcripts show the full back-and-forth between the user and the design assistant — they tell you what the user actually wants and where they landed after iterating. Don't skip them. The final HTML files are the output, but the chat is where the intent lives.

Read project/u30B7u30D5u30C8u7BA1u7406u30A2u30D7u30EA.dc.html in full. The user had this file open when they triggered the handoff, so it's almost certainly the primary design they want built. Read it top to bottom — don't skim. Then follow its imports: open every file it pulls in (shared components, CSS, scripts) so you understand how the pieces fit together before you start implementing.

If anything is ambiguous, ask the user to confirm before you start implementing. It's much cheaper to clarify scope up front than to build the wrong thing.

About the design files

The design medium is HTML/CSS/JS — these are prototypes, not production code. Your job is to recreate them pixel-perfectly in whatever technology makes sense for the target codebase (React, Vue, native, whatever fits). Match the visual output; don't copy the prototype's internal structure unless it happens to fit.

Don't render these files in a browser or take screenshots unless the user asks you to. Everything you need — dimensions, colors, layout rules — is spelled out in the source. Read the HTML and CSS directly; a screenshot won't tell you anything they don't.
