c599c2ba09 fix(pdf): export linetypes and true lineweights (#155)
The internal PDF export set each wire's colour and thickness but never a
dash pattern, so every dashed / centre / dash-dot line printed solid. It
also derived thickness from the on-screen pixel weight, which carries a 2×
screen-legibility boost — so print weights were inconsistent and barely
differentiated.

Emit a PDF dash pattern per wire from its linetype run lengths (mm→pt,
real length = index of the last non-zero element + 1, 1 pt floor so a dot
still marks), resetting to solid where there is no pattern. Convert
lineweight with a factor that undoes both the 96-dpi scaling and the
display boost, so print thickness is the true physical mm.

44fa9df278 build(web): restore the wasm build — gate native-only deps off wasm
The web build had bit-rotted: native-only features added since it last
compiled pulled crates that don't build for wasm32-unknown-unknown.

- printpdf (PDF export / printing) → native-only target; the web build gets
  stub export_pdf / print_wires. It pulls a wasm-incompatible memchr 1.0.2
  via lopdf → nom_locate, and the web has no filesystem.
- getrandom 0.3 (via ahash via acadrust) → enable its wasm_js feature and add
  the matching --cfg getrandom_backend rustflag in .cargo/config.toml.
- ocs_plugin_api "host" feature (out-of-process plugin runtime: interprocess,
  libloading, memmap2, rkyv) → native-only target; the web gets the
  dependency-free manifest/ribbon contract. The host code was already
  wasm-gated; only the Cargo wiring pulled it in unconditionally.

`trunk build --release` succeeds again.

b2e20c95fe feat(wasm): compile the library for wasm32 (issue #45 groundwork)
First step toward a web build: the library now compiles for
wasm32-unknown-unknown with --no-default-features.

- Add a `solid3d` feature (default on) gating truck-meshalgo /
  truck-shapeops / lzma-sys. These pull vtkio → xz2 → lzma-sys (C),
  which cannot cross-compile to wasm. Without the feature the 3-D
  solid path (tessellation, booleans, ACIS import) becomes no-ops;
  2-D CAD is unaffected. Native builds keep the feature by default.
- Move native-only crates (ureq, open) to non-wasm target deps and
  add cfg shims: update-check is a no-op on wasm, and a new `sys`
  module provides open_url + handle_path (rfd FileHandle → PathBuf;
  synthesizes a name-based path on the web).

Native build + all 75 tests unchanged. Browser runtime wiring
(entry point, trunk, real file I/O) is a follow-up.

7fe7e0230d refactor(scene): group modules into role-based subfolders
Move the 30 flat modules under src/scene/ into six folders by role:
convert (entity→geometry), text (fonts/shaping), model (render models),
pick (hit-test/selection/grips/xclip), view (camera/transform/render),
cache (block + property caches). pipeline/ is unchanged.

Full path migration — all `scene::X` references become
`scene::<group>::X`, no compatibility re-exports. render.rs items that
were `pub(super)` (parent was scene) become `pub(in crate::scene)` to
keep their original scene-wide visibility.

No behavior change; build and tests are green.

ef1f9a08d6 chore: rename H7CAD to Open CAD Studio
Joining the OpenAEC Foundation (open-aec.com). Crate/struct become
OpenCADStudio, user-facing strings use the spaced "Open CAD Studio"
form, repo URLs point to HakanSeven12/open-cad-studio. Logo (window
icon + assets/logo.svg) redrawn with OCS initials. Drop examples/
binaries — unused.

30f7ad0918 feat(hatch): rasterise PAT pattern lines for paper canvas + PDF
Both the on-screen paper canvas and the PDF / print pipeline only knew how
to draw the boundary outline of pattern hatches (ANSI31, ANSI37, dotted
brick, etc.) — the actual hatch lines were a GPU-only feature, so any
paper-space view or PDF export showed a hollow polygon where there should
be ruled fill.

Add a CPU rasteriser as `HatchModel::pattern_segments()`:

- builds an edge list from the boundary, splitting at NaN sentinels and
  closing each sub-path so even-odd inside tests handle islands / holes;
- for every PAT family computes the world-space step vector
  (`(dx,dy)` rotated into the family's frame, scaled by `model.scale`)
  and the inclusive k-range bounded by the boundary AABB plus a 4096-
  line safety cap;
- intersects each line with every boundary edge, sorts the hit
  parameters, walks them in pairs (even-odd) and emits one segment per
  in/out interval. Dash patterns are walked along each clipped span with
  phase preserved via `t mod period`, matching the GPU shader's
  absolute-t dash evaluation;
- pattern origin (`family.x0 / y0`) is rotated by `angle_offset` and
  scaled the same way as `hatch_batched.wgsl`, so PAT patterns with
  non-zero origins (brick / offset herringbone) line up with the GPU
  render.

`paper_canvas::draw_hatch` and `pdf_export::emit_hatch` now route
pattern hatches through this rasteriser; solid / gradient hatches keep
their existing fast paths. The previous outline-only behaviour was a
visible regression on every layout containing a ruled fill.

c2f3844cb6 feat(io): export hatch + wipeout fills to PDF
The PDF / print pipeline only walked `WireModel.points` (lines), so every
hatched region disappeared the moment a sheet left H7CAD. Route the same
`paper_canvas_hatches()` / `paper_canvas_wipeouts()` lists that the
on-screen canvas consumes into `pdf_export::export_pdf` and
`print_to_printer::print_wires`, and emit each one as an
`Op::DrawPolygon` with the EvenOdd winding rule so multi-ring boundaries
(islands / holes) render correctly:

- Solid       → fill the boundary polygon in the hatch colour.
- Pattern     → stroke the outline (PAT line families stay procedural;
                follow-up work will rasterise them into segments).
- Gradient    → fill with the averaged colour, mirroring paper_canvas.

Wipeouts emit first, then hatches, then wires — same z-order as the
on-screen canvas, so wires draw on top of the fills they belong to.

1db3ad6a33 Feat: implement CTB/STB plot style table with PDF export integration
- src/io/plot_style.rs: PlotStyleTable and PlotStyleEntry data structures;
  CTB reader (deflate/zlib decompressed text format) with ACI→RGB and
  ACI→lineweight lookup; CTB writer (zlib compressed); LW_TABLE constant
- src/io/pdf_export.rs: accept optional PlotStyleTable; apply ACI color
  and lineweight overrides during PDF rendering
- src/scene/wire_model.rs: add `aci: u8` field to carry ACI index
- src/scene/render.rs: render_style() now returns ACI alongside RGBA
- src/scene/mod.rs + tessellate.rs: propagate aci through wire building
- app: PlotStyleLoad/Loaded/Clear messages and handlers;
  PLOTSTYLE LOAD | CLEAR | STATUS command; active_plot_style state on H7CAD
- flate2 added as dependency

617d7ba56a Feat: Phase 2 — expanded PageSetup panel and PlotSettings integration
PageSetup panel:
- Paper size presets (A4/A3/A2/A1/A0 portrait+landscape, Letter)
- Plot area selector: Layout vs Extents
- Center-on-page toggle
- Plot offset X/Y fields
- Rotation picker: 0° / 90° / 180° / 270°

PlotSettings (acadrust object):
- PageSetupCommit finds or creates a PlotSettings object in the document
- Writes paper size, plot type, centering, offset, rotation to it
- DXF round-trip: PlotSettings persisted to file

PDF export:
- Reads PlotSettings for the active layout
- Applies centering (auto-computes offset from wire extents)
- Applies offset X/Y from PlotSettings
- Applies rotation via PDF CTM transformation matrix
- Swaps paper dimensions for 90°/270° rotation

845770938c Fix: paper limits, Cohen-Sutherland clipping, frozen layers UI, PDF improvements
Paper limits:
- Change A4 fallback from 12×9 to 297×210 mm in paper_limits()

Context menu:
- Translate layout context menu labels to English (Rename / Delete)

Viewport clipping:
- Replace AABB-only culling with proper Cohen-Sutherland line clipping
  in viewport_content_wires(); each projected segment is now clipped at
  the exact viewport boundary instead of being included or discarded whole
- Add cs_clip() and clip_polyline_to_rect() free functions in scene/mod.rs

Frozen layers per-viewport UI:
- Inject a "Frozen Layers" EditText property in the Properties panel for
  viewport entities (layer names resolved from handles at display time)
- Handle "frozen_layers" in PropGeomCommit: parse comma-separated names,
  resolve to layer handles, update vp.frozen_layers in-place

PDF export improvements:
- Add offset_x/offset_y params to export_pdf() for model-space normalization:
  coordinates are shifted so the drawing origin maps to the page origin
- Model space export computes extents via model_space_extents() (now public)
  and adds a 5 % margin; falls back to A4 landscape for empty drawings
- Skip __paper_boundary__ wire in PDF (white background covers it)
- Map yellow (active viewport border) → black and cyan (vp border) → dark
  blue for print-friendly output

e1d296da10 Phase 7: Plot settings and PDF export
- Add printpdf 0.9.1 dependency for native PDF generation.
- New src/io/pdf_export.rs: converts paper-space WireModels to a PDF
  page (per-wire stroke color, line weight in Pt, NaN-split segments).
  White/near-white colors are inverted to black for print output.
- Add PlotExport / PlotExportPath messages: opens a save-file dialog
  and writes a .pdf next to the drawing file.
- Add PageSetupOpen/Close/WidthEdit/HeightEdit/Commit messages: a
  centered modal panel lets the user enter paper width and height (mm);
  on commit the Layout object's min/max_limits are updated in-place.
- Register PRINT / PLOT / EXPORT and PAGESETUP (PS) commands in
  dispatch_command; fix MVIEW error message to English.
- Layout ribbon gains a "Plot" group with Page Setup and Export PDF
  ribbon buttons.
