Switching to a Layout re-tessellated the whole model — `memo_miss=186455`,
2034 ms — to arrive at geometry identical to what was already in the memo.
The only thing that differed was colour.
`local_wires_for` already knows this: it stores the raw colour and drops
its background argument with `let _ = bg_color;`, noting that
`Batches::finalize` applies `adapt_to_bg` last, "so the cache no longer
has to rebuild on BACKGROUND / layout-switch". The tessellation memo's
guard had not been told, and still mixed the background in, so every
entry was discarded on a switch.
`finalize` now records what its colour resolution consumed — the raw
colour, the raw glyph colours, and the three flags it branches on — as
`WireModel::bg_adapt`, and `resolve_colors_for_bg` replays it for another
background. The guard drops the background, so a memo entry serves any
layout.
The resolution recomputes from the recorded raw colour rather than from
the resolved one, which makes it idempotent and therefore safe over a set
that mixes memo hits with freshly tessellated misses. Re-adapting the
resolved colour would not be safe: `adapt_to_bg` snaps a near-white colour
to pure black on a light background, and pure black comes back pure
*white* on a dark one, losing the tint. A test pins that asymmetry so the
raw colour is not optimised away later.
The contract is tested against the real `finalize` rather than a copy of
its logic: for every background pair, building under one and resolving for
the other lands exactly where building under the other would have.
`bg_adapt` is `None` for wires built anywhere else, and the resolution
skips them, so nothing outside the block cache changes colour. It is also
`None` when the resolution would be a no-op — a preserved colour with no
canvas fill looks the same under every background — which keeps the common
case at no cost.
Ordering is unchanged: the pass runs inside the builder, before
`append_scene_markers` and `apply_refedit_fade`, both of which have their
own separate background dependency.
`wires-build` gains `colors=` so the pass has a number of its own.

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.

Enable in-place editing of inherited properties in the Properties panel:
- Transparency: Switch to PropValue::EditChoice with ByLayer and ByBlock presets to allow direct typing of any numeric percentage value (0..90%) without combo_box autocomplete interference.
- Select-all-on-click: Integrate EditChoice text inputs into build_field_key_map with dedicated widget IDs, preserving click-to-select-all across editable fields.
- Material: Provide bounded preset choices (ByLayer, ByBlock, Global, and active custom material) to avoid scanning large drawing dictionaries.
- Plot style: Implement mode-aware behavior with interactive Choice in STB mode and ReadOnlyWithTooltip in CTB mode.
- Read-only tooltips: Introduce PropValue::ReadOnlyWithTooltip to provide contextual explanations for locked fields while preserving mouse text selection and clipboard copying.
- Dropdown alignment & unified borders: Fix EditChoice internal input/caret background clipping so the container's 1px neutral/active border surrounds the entire control identically to Lineweight and text inputs.
- Document defaults & aggregation: Synchronize document header defaults when editing with No selection, and aggregate heterogeneous multi-selections (*VARIES*).
Share source buffers across block placements and render nested content with GPU instance transforms.\n\nChunk silhouettes and compact mesh material data so large drawings stay under device buffer limits and remain responsive.
Route model, paper, viewport and nested block content through one traversal while preserving leaf renderers. Carry decoded material state into mesh shading and harden solid geometry conversion.
- Keep the floating panel near the selection and inside the viewport

Selecting a proxy object we render from its cached graphics (an AEC
Wall/Door/Window and the like) showed "Unknown" as its type. The entity
now carries its real DXF class name from the CLASSES section (acadrust
bump), so surface it: ui_name_or_class title-cases the class ("AEC_WALL"
→ "Aec Wall") for the properties Type row and the status-bar label, and
still says "Unknown" only when the class truly can't be named.

Two rendering defects surfaced on the budweiser benchmark drawings, both
tied to a drawing's annotation scale.
Annotative scale representations. A drawing may materialise each annotation
scale as its own object (here a block insert per scale, on a "0 @ <scale>"
layer, each carrying a per-object AcDbContextData bound to one scale).
Nothing filtered them, so every scale drew at once — a 1× copy stacked
under a 10× one. Add annotative::annotative_offscale and apply it in the
three paths that expand block content: the wire block-defn cache, the
resident/top-level visibility gate (model space only — paper viewports use
their per-viewport frozen scale layers), and the exploded-insert hatch/fill
walk (filtered before normalize strips the handle). An object is shown when
a representation matches the current scale; the off-scale ones are hidden.
When the current scale is unsupported by any representation, fall back to
the base "1:1" copy instead of hiding everything (the object must not
vanish) or showing everything (the copies must not stack).
Model-space linetype scale. PSLTSCALE (a paper-space flag) was applied to
model-space linetypes via the annotation scale, so a drawing saved at e.g.
CANNOSCALE 10:1 drew its linetypes 10× off. Thread a `paper_space` flag
through tessellate_entity and gate the PSLTSCALE factor on it, so it only
scales linetypes for content shown inside a paper-space viewport; model
space keeps LTSCALE × CELTSCALE.

A dimension bakes its geometry into a per-instance *D block, offset into
the owning block by the dimension insertion_point. When that dimension
sits inside a block (INSERT → block → Dimension → *D), only its top-level
form drew; nested it rendered nothing, and once the lines/text/arrow
outlines were routed through the block cache the arrowhead FILLS were
still missing:
- 2D SOLID arrowheads: block_cache's Dimension arm now expands the *D
block, translating each sub by insertion_point (WCS → block-local) and
routing Insert subs through build_nested_ref, others through
tessellate_sub_local (which emits the solid fill_tris).
- Insert(hatch) arrowheads (custom arrow blocks = LwPolyline + Hatch):
the hatch renders via the separate GPU explosion path, which only
descends INSERT→INSERT→Hatch trees and so never reached a hatch behind
a Dimension. block_has_hatch now recurses through a Dimension into its
*D block, and the fill explosion's new explode_including_dims lifts
each dimension child's *D content into the owning block's frame
(translate insertion_point, then apply the insert transform) so its
arrow inserts / hatches ride the normal walk.
Table *T baked blocks get the mirror treatment in block_cache.

A constant ATTDEF renders as block content, but with an empty default
value there is nothing to draw — the ATTDEF tessellator would fall back
to its tag-placeholder preview (meant for standalone definitions), so
blocks showed the literal tag text where AutoCAD shows nothing.

Xref merge now inserts entities in the source block's chain order and
carries SortEntitiesTable objects across (remapped to merged handles).
draw_depth_map values become [depth, half] so exploded block/xref fills
and wide-polyline band wires both compose child depth as
insert_depth + in-block rank x half, recursing into nested inserts with
the same divisor - bands and fills from one block interleave by the
block's internal order instead of stacking at the insert's single depth.
Band batches split per rank via WireModel.depth_override; thin wires
stay merged. The wire arena falls back to a full rebuild when a slab
carries mixed depths so refreshes don't flatten band overrides.

Section marks and drawing-view borders are now real acadrust entity
types instead of Unknown-with-extras, so the renderer dispatches on the
variant directly, the arrow-direction resolver reads the active viewport
off the ViewBorder entity, and selection / properties show "Section
Symbol" and "View Border" instead of "Unknown". View borders are
non-plotting and tessellate to nothing; both count toward the lossy
Save-As warning since they round-trip via their raw records.
Bumps acadrust for the entity promotion.

A wide polyline with per-vertex varying widths rendered at its widest edge
(uniform-width ones were already exact). Draw the true taper instead.
`WireModel.taper_widths` carries a per-point full band width. The wire
instance (native slim + web fat) gains per-endpoint `world_hw_a/b`, and both
wire shaders interpolate `mix(hw_a, hw_b, which_end)` so each segment's band
narrows/widens linearly — depth-tested, and the linetype dash still applies.
Alignment (widths must match the tessellated points) is solved by building
both together: a new `TruckObject::TaperedLines(points, widths)`, filled by
`common::tapered_band_points` (straight = endpoints, arc = 16 samples with the
width lerped along it). to_truck routes a varying-width polyline here —
LwPolyline before the PLINEGEN split, Polyline2D at its return — while a
uniform-width one keeps the constant-band Contour path unchanged. `world_width`
stays the widest edge as the PDF-stroke + zoom-floor fallback.
Blocks fall back to the constant-widest band (`LocalWire` carries no
taper_widths).

Extends the wide-polyline shader band to the two cases the first pass left on
the hatch pipeline.
Polyline2D:
- A flat wide Polyline2D now draws its band from the centre-line wire
(`world_width`), same as LwPolyline (`polyline_band_width` handles both).
- A thickened wide Polyline2D extrudes a solid 3-D tube. `thick_wide_band`'s
body moves to a shared `common::thick_band_tube(origin, fills, thickness,
normal, to_wcs)`; LwPolyline delegates to it and Polyline2D calls it from
its thickness path. Tube edges read black for both kinds.
- The model-space wide-band hatch loop is deleted (both kinds now wire/tube).
Blocks:
- Block-internal wide polylines draw the shader band too. `LocalWire` carries
`world_width`; `emit_wire` scales it by the insert transform (average of the
X/Y axis image lengths) so the band tracks a scaled insert, and the scaled
width joins the batch `style_key`. `push_block_wide_fills` (the block hatch
band) is removed.

A wide polyline's flat band was drawn by the hatch pipeline: a solid fill
with only draw-order depth. It ignored the entity linetype (the width
"crushed" the dash pattern) and showed through 3-D geometry in a tilted view.
Draw the band from the polyline's own centre-line wire instead. A new
`WireModel.world_width` (drawing units) makes the wire vertex shader expand
the quad by `world_half_width / world_per_pixel` (clamped to a hairline), so
the band is sized in world units and tracks zoom. Because it is now a wire:
- the GPU dash shader dashes the band by arc-length — the linetype applies;
- it is depth-tested at the polyline elevation — no draw-order see-through;
- no CPU band triangles or per-dash geometry are generated.
`world_half_width` rides in `WireConst` (native, replacing a pad) and the web
`WireInstance` (loc 14); both wire shaders branch on it. The tessellator sets
`world_width` from the LwPolyline width on the Contour / SegmentedLines arms,
and the model-space fill loop no longer emits a hatch band for any LwPolyline.
Pick still uses the band polygon (`pick_tris`).
Blocks keep the hatch band: `LocalWire` carries no `world_width` (finalize
zeroes it), so a scaled insert still scales its band correctly.

Rectangular paper viewports now go through the same GPU stencil clip as
non-rectangular ones: viewport_clip_boundary_ndc returns the four rect
corners (a full-target mask) instead of nothing, so the render path has
no rect/non-rect special case — every content viewport carries a clip
boundary and draws with stencil reference 0xFF.
With a single clip path, the old per-wire / -image / -wipeout scissor
mechanism is fully dead and removed: compute_*_scissors, the
*_pixel_scissors buffers, the project_scissor helper, the per-pass
set_scissor_rect blocks, the vp_scissor field threaded through
WireModel / ImageModel / HatchModel and their GPU mirrors (WireGpu /
ImageGpu / WipeoutGpu / HatchWebGpu), from_run's scissor parameter, the
scissor grouping in build_wire_buffers, and the is_arena_eligible gate.
Net -245 lines across 54 files.
Rectangular viewports still clip exactly via their own render rectangle;
the stencil mask is a redundant full-target no-op there, kept only so
the clip code path stays uniform. XCLIP keeps its CPU wire clip.
