Features

The "features" lens covers cross-cutting capabilities — things that span multiple systems and packages, and that make the most sense to read about as a whole rather than on a per-component page.

Page	What's covered
npm support	npm: specifiers, registry client, dependency resolution, BYONM, node_modules/, deno install/add/remove
JSR support	jsr: specifiers, the JSR registry, deno publish, JSR-specific lockfile handling
Node compatibility	The ext/node polyfills, the resolver, tests/node_compat/, the recurring fix-pattern in commit history
Standalone binary (deno compile)	Module-graph capture, eszip embedding, denort, cross-platform builds
Workspace support	deno.json workspace, package-level config, task inheritance

These overlap with the systems and extensions pages but approach the same ground from a "user-facing capability" angle.
