New modules: core, annotations, resources, navigation, model. The small test modules (version_tests, open_action_javascript_tests, substitution_tests, open_dest_tests) moved with the code they test.

//! Document inspection: everything panels need that is not pixels.
|
|
//!
|
|
//! Page geometry comes from hayro (which resolves inheritance and rotation); the rest comes from
|
|
//! the lazy COS reader through a read-only lopdf object adapter. The original lopdf loader
|
|
//! remains the compatibility fallback. When neither can inspect a renderable file, panels
|
|
//! are empty and `warnings` says why.
