" summary

Advocates progressive enhancement and server-side rendering with deferred JavaScript — Twitter cuts time to first tweet 1/5 by rendering first and running JS later. Gives two concrete practices: handle focus properly (use hashchange or click handlers, set tabindex="-1" and programmatically focus while often preventing default to avoid Chrome/Firefox quirks), and expose dynamic updates via live regions (use aria-live="polite"). Cites BBC Olympics fallback approach and zero complaints as proof it works.
