Overview

Semantic PDF types — one subclass per Arlington TSV. Each class declares arlington_object "Name" and gets its field metadata auto-loaded from the vendored TSVs at first access.

The arlington_registry maps TSV name -> Type subclass so other Types' field-link resolution can find concrete classes.

Adding a new PDF type = adding one subclass that calls arlington_object "TSVName". Open/closed: no switch edits.
