Delivered a new tabular data capability and fixed docs rendering to improve data presentation and content accuracy. Key work included: (1) amplify-ui: table type added to Collection UI primitive with component/type definitions and tests to support tabular data and custom headers (commit 8319d5afaa9f3de59f18d72d873953a1fd0e1b73); (2) docs: apostrophe display fix on main page by replacing HTML entity with direct character (commit 9b931a584a3d64a1e7000c924101e98dbcdd818f). This strengthens UX, reduces support risk, and demonstrates robust TS/types, testing, and content QA.
