SpacetimeDB Paint App - Base Prompt

Create me a real-time collaborative paint/drawing app using SpacetimeDB as the backend.

Project root is:

apps/paint-app/

Create the project under a timestamped folder:

apps/paint-app/spacetime/paint-app-YYYYMMDD-HHMMSS/

Use paint-app as the module name for SpacetimeDB.

Constraints

• Work entirely inside your timestamped folder. Do not touch any other existing code.
• Only create/modify code under:
  • apps/paint-app/spacetime/paint-app-YYYYMMDD-HHMMSS/backend/spacetimedb/ (server-side TypeScript)
  • apps/paint-app/spacetime/paint-app-YYYYMMDD-HHMMSS/client/src/ (client-side TypeScript/React)
• Keep it minimal and readable.

UI Requirements

Use SpacetimeDB brand styling (dark theme).
