Sass migration

Separate syntax conversion from semantic adoption.

Inventory variables, nesting, mixins, imports, and generated surfaces without pretending every Sass abstraction is a utility.

Map the source surface

The inventory records statically visible Sass roles and unresolved dynamic behavior so the team can choose what stays authored CSS.

Ordinary CSS is a valid destination

Use the standard-CSS transformer for syntax and compatibility work. Adopt typed PliegoCSS styles only where identity and provenance pay for themselves.

Keep originals and rollback evidence

Applied replacements preserve source backups and hash-bound rollback records. A changed destination aborts rather than overwriting concurrent edits.
