Bare-domain URLs like rspace.online/rsocials/thread now render an info
page with CTAs instead of silently serving the functional app. The
functional app only appears inside a {space} context (e.g.
demo.rspace.online/rsocials/thread). API routes still pass through.
- Add SubPageInfo interface to shared/module.ts
- Add renderSubPageInfo() renderer to server/shell.ts
- Modify bare-domain routing: api/ passthrough → info page → demo fallback
- Add subPageInfos to 8 modules (rsocials, rflows, rnetwork, rtrips,
rbooks, rphotos, rinbox, rsplat)
- Add window.__rspaceSaveGate() auth prompt on write operations
- Wire save-gate into rsocials Thread Builder save handler
