🏷️ Prefer "import type" over raw "import"

[dubzzz]

While raw "import" works well, it does carry an extra cost:

• bundlers may not optimize it as much as they can and may require to import the linked file even if they don't need to assess typings
• it may produce less optimized bundles (we may refer to unneeded files and thus delay some operations)
