• llms.txt browser: Cmd+L opens URL input to fetch llms.txt from any domain

• Both /llms.txt and /llms-full.txt fetched in parallel; Tab switches between them in the markdown viewer

• URL input overlay: Cmd+V paste, backspace key repeat, domain normalization (strips protocol and known paths)

• Hint mode: hold Cmd to show tab number badges

• n/N match navigation in markdown viewer normal mode (after closing search bar)
