Public sheets render as static placeholder instead of interactive spreadsheet

[typelets]

Problem

Public sheet links (/p/{slug}) display a static "Loading spreadsheet..." placeholder instead of the interactive spreadsheet viewer.

Root Cause

The Cloudflare Worker SSR intercepts all /p/* routes and returns server-rendered HTML for SEO. This works for notes/diagrams/code because the content is static HTML.

However, sheets require:

1. The React SPA to load
2. PublicSheetsViewer component to hydrate
3. Univer.js to render the spreadsheet

The SSR HTML doesn't include the React app bundle (<script type="module" src="/assets/index-*.js">), so the page never hydrates and the spreadsheet never renders.

Solution

For sheets, bypass SSR and pass the request through to the SPA origin:

if (note.type === 'sheets') {
  return fetch(request);
}

Trade-off

Sheets won't have SSR for crawlers/SEO. If SEO for sheets is needed later, we could:

1. Fetch the origin's index.html and inject it into SSR response
2. Generate a preview image/table of the sheet data for SSR
