Resolve ByBlock alpha independently from color and keep explicit opaque values from falling back to layer transparency.
Pin the matching cadcodec API across desktop, plugin, and web targets.

Keep hidden pre-drag geometry out of snap candidates and avoid empty
scene invalidations. Require stable OTRACK dwell observations and cache
planar-solid visibility during live previews.

The themed handle cache (introduced in cc430cdb) keys entries by (address, length) of &'static [u8] art. However, the art was declared as const; Rust may inline distinct copies of a const at each use site, giving the same logical icon different addresses. This broke cache lookups for wrapper functions (e.g., themed_arrow_down) that refer to the same icon from a different module than the cache test. Convert the ~30 themed-relevant byte slices (TRI_*, HOME, UNDO, REDO, CHECK, etc.) to static so each artwork has one stable address process-wide.
Also refactor themed_handle to drop the immutable borrow before building a miss handle, preventing a reentrant call from panicking on a second borrow_mut.
Adjust themed_cache_tests to use delta assertions and per-test cache removal for isolation, and add coverage for second-call cache hits, wrapper delegation, and the length component of the key.

Improve the selection-cycling list box so overlapping objects can be
identified at a glance:
- Add a color swatch per row showing the object's effective drawn color
- Show the layer name right-aligned next to the element type
- Size the popup to fit its content with consistent padding
Widen render_style_for_viewport visibility from scene-internal to
crate-wide so the view layer resolves the same color the renderer uses.
