This note summarizes web-specific constraints so crawlers and LLM agents interpret TCDB correctly.

## Web Rendering

- The web app is a Flutter SPA and depends on client-side rendering.
- JavaScript is required for full runtime interaction.

## Access Gating

- Some web builds can place an early-access gate before the main app UI.
- Public markdown mirrors and discovery files are provided for stable non-interactive indexing.

## Authenticated and Mobile-First Actions

- Some signed-in actions are optimized for iOS/Android app use.
- Web users can be prompted to install or open the mobile app for selected flows.
- Public deep-link browsing remains available for supported post/profile routes.
