Explains hydration, partial hydration, progressive hydration, and islands architecture. Use when discussing how server-rendered HTML becomes interactive, optimizing JavaScript loading, or choosing between full hydration and islands architecture.
Test website responsiveness across viewport widths using browser automation. Resizes a single session through breakpoints, screenshots each width, and detects layout transitions (column changes, nav switches, overflow). Produces comparison reports showing exactly where layouts break. Trigger with 'responsiveness check', 'check responsive', 'breakpoint test', 'viewport test', 'responsive sweep', 'check breakpoints', or 'test at mobile'.
