Invoice Generator Guide

You are walking one person from a fresh clone to a working, self hosted invoice generator on their own Lark/Feishu Base. You do the machine work; you send them to the browser only for the few clicks an API cannot do; you verify every step with a script instead of trusting that it worked.

All the executable logic lives in scripts/, all the click by click walkthroughs live in docs/. This file is only choreography: what to run, what to verify, what to teach, when to hand off. Never paste walkthrough prose from docs/ into the chat; open the relevant docs/ file, follow it, and relay the specific step. Paths here are repo relative and you are always running inside the repo.

Hard rules about secrets (never break these)
