With OCS_TEXT_SDF on, top-level text took the full path only at ≥5 px and
still drew greeked OBB rects / baseline lines when zoomed out — doubling
with the SDF glyphs. Force the text LOD height to None while SDF is on so
text always falls through to the full path, which is itself suppressed to
an empty snap-only wire; SDF then renders it crisply at every zoom.
(Block-internal text is unaffected — it is not collected for SDF, so its
wire/greek path stays.)
Verified in-app: zoomed-out SDF text stays crisp with no greek/baseline
double draw. Flag off: unchanged.

Locked-layer objects were fully editable. Now they stay visible and
snappable but are otherwise protected:
- Not selectable: the five interactive pick paths (box, lasso, single
click, cycling, box-release) plus SELECTALL and QSELECT skip locked
entities.
- Not modifiable (defense-in-depth even if a handle slips through):
transform_entities, erase_entities, apply_grip and the Properties
commit all skip locked entities.
- Faded: entities on a locked layer render dimmed toward the background
(render_style + wire tessellation); toggling lock re-tessellates.
- Snap still works: locked entities are intentionally kept in the wire
set (visibility_ok untouched), so object snap keeps finding them.
- Feedback: a small padlock is drawn by the crosshair when hovering a
locked object, and clicking one prints "Object is on locked layer …".
New Scene::is_layer_locked / locked_layer_name helpers centralise the
check (mirroring layer_hidden).

Entities inside a block definition that sit on layer "0" must take on the
properties of the layer the block reference is inserted on; every other
layer is "sticky" and keeps its own identity. OpenCADStudio resolved a
block child's ByLayer color/linetype/lineweight against the child's own
layer in all cases, so layer-0 content stayed layer-0 (white) instead of
inheriting the instance layer.
Resolution now follows the standard rule for block children — explicit
wins, then ByBlock → the insert's own style, then layer-0 + ByLayer →
the insert's *layer* style, else the child's own layer. The insert's
layer style threads through the whole block-expansion chain (and chains
correctly through nested inserts), with the child's own transparency
preserved.
Covered across every block-render path:
- wires (line/arc/circle/polyline/text) via the block cache + the
explode fallback + insert attributes
- hatch / solid fills (also fixes the PDF/print export path)
- 3D solid block children (per-instance mesh recolor)
- Dimension / Table baked-block sub-entities
New shared helpers in scene::view::render: InheritStyle, layer_render_style,
lineweight_to_px; render_style_for_block_sub gained the layer-0 branch.
Adds unit tests covering the layer-0, sticky-layer, ByBlock, explicit and
transparency cases.

scene/tess.rs held the free parallel-tessellation functions
(tessellate_entity, lod_stub_wire, entity_aabb, …) that the giant-file
split had left at the scene root. They belong with the rest of the
tessellation code, so move the file to scene/convert/tess.rs alongside
tessellate.rs / tess_util.rs and re-point the re-export.
Leaves the scene/ root as a consistent set of `impl Scene` method
groups; the free-function outlier is gone.
