Changes

Summary

• The Amplitude source guide shows only 3 tables in "Available tables". The source has 8 tables. Readers can miss the 5 taxonomy tables, which include the new group_properties table.
• This PR adds the 5 missing tables to the manual table, with their sync method. All 5 tables use full refresh.
• The intro now names the Taxonomy API with the other Amplitude APIs.

Table added	Sync method
event_types	Full refresh
event_properties	Full refresh
user_properties	Full refresh
event_categories	Full refresh
group_properties	Full refresh

• Source of truth: AMPLITUDE_ENDPOINTS in the Amplitude settings.py. Only events has incremental fields.
• This is a content PR. It changes one Markdown file. It has no visual change to site UI.

Agent context

• I kept the manual table and did not remove it. The generated <SourceTables /> block also shows the sync method, but the manual table gives a short description of each table and the 30-day initial sync limit for events. If maintainers prefer one source of truth, the manual table can go in a follow-up PR.

Checks

• npx prettier@2 --check on the changed file: pass.
• I did not run the dev server. The sandbox has no installed dependencies. The change is a Markdown table and one sentence.

Checklist

• I've read the docs and/or content style guides.
• Words are spelled using American English
• Use relative URLs for internal links
• I've checked the pages added or changed in the Vercel preview build
• If I moved a page, I added a redirect in vercel.json (no page moved)

Eager-graph budgets are report-only until a baseline is established. Sizes are gzip of public/**/*.js; eager size is webpack module source bytes for the modules actually shipped in the entrypoint's initial chunks (post-tree-shake).
