camouflage.nvim

A Neovim plugin that visually masks sensitive values during screen
sharing, using extmarks: .env, JSON, YAML, TOML, properties, netrc,
XML, .http, Terraform/HCL and Dockerfiles, plus picker previews and
result rows, the quickfix list, diffs and terminal output. It has a
presentation mode and a screen shield. The actual file content is
never modified.
