Read these files before editing: 1. `.trellis/spec/README.md` 2. `.trellis/spec/shared/index.md` 3. `.trellis/spec/backend/index.md` for backend work 4. `.trellis/spec/frontend/index.md` for frontend work 5. `.trellis/spec/shared/verification.md` before completion Key branch rule: `main` must stay anonymous and personal-deployment friendly. Do not add hosted auth, Supabase, Stripe, LinuxDo, profile, quota, admin, or billing requirements unless the task explicitly targets both branches. --- > Source: [Tendo33/IdeaGo](https://github.com/Tendo33/IdeaGo) — distributed by [TomeVault](https://tomevault.io).
