AutoCAD stores a layout's sheet as the plotter driver's canonical media
name (`ISO_A4_(210.00_x_297.00_MM)`, `ANSI_full_bleed_B_(11.00_x_17.00_Inches)`),
so a drawing saved here has to carry the same spelling for AutoCAD to find
the sheet in its DWG To PDF list, and a name that arrives from AutoCAD must
resolve to its dimensions and go back out untouched.
- New `io::paper_catalog` replaces the eight-entry `paper_sizes`: ISO A/B,
ANSI, ARCH (incl. E1) and JIS series with full-bleed / expand variants,
Letter / Legal / Tabloid, millimetre and inch units, a parser that
reconstructs any well-formed AutoCAD name (custom or driver-specific)
from its embedded dimensions, driver / legacy-config aliases (`A4`,
`Letter`, `Ledger`), and dimension matching that prefers the plain sheet.
- The Plot dialog stores the canonical name and shows the sheet as
`ISO A4 (210 × 297 mm)`; a sheet that only exists in the drawing is
listed first so it stays selectable.
- A sheet the user did not change keeps the drawing's own media name
(`paper_name_for_settings`), so a Windows printer's `A4` is not rewritten
to `ISO_A4_(…)` just by passing through the dialog.
- Drops the unused `PlotFormat` / `PlotOrientation` messages,
`paper_label_from_dims`, and three duplicated `match "A4" | …` tables.
Tests: catalogue spelling, parser round-trip, aliases, dimension matching,
display formatting, plus dialog ↔ layout round-trips for driver-named,
catalogue and unknown sheets.

Model space appearance now follows the active UI theme instead of a
hardcoded dark background. Canvas mode is user-selectable (Match Theme /
Classic CAD Dark / Custom RGB), with matching controls for the paper
sheet and desk surround backgrounds and grid opacity.
Implements industry-standard CAD system variables, all settable via
command name, SETVAR, and the Options dialog:
- COLORTHEME (0/1 dark/light UI scheme, preserves custom palettes)
- COLORSCHEME (interactive named-theme selection)
- BACKGROUND (THEME/CLASSIC/DEFAULT/DESK presets, RGB triplets)
- SELECTIONAREA, SELECTIONAREAOPACITY (translucent marquee fill)
- WINDOWSAREACOLOR/WINDOWAREACOLOR, CROSSINGAREACOLOR (ACI or theme)
- SELECTIONEFFECT, SELECTIONEFFECTCOLOR (GPU highlight pass, driven by
selection_generation invalidation — no retessellation)
- SELECTIONPREVIEW (bit 0 = idle rollover, bit 1 = in-command hover)
- GRIPSIZE, GRIPCOLOR, GRIPHOT, GRIPHOVER (grip overlay styling)
Restructure the plot dialog into a style-manager-style master/detail: a
left list of page setups plus a right settings editor. The list shows
<none> (defaults + PDF) and <previous> (the settings the dialog opened
with), then the drawing's layouts (*Model*, *Layout1*, …) and its
standalone named page setups.
- Named page setups live in the ACAD_PLOTSETTINGS dictionary
(src/scene/page_setup.rs: names/get/save/delete/rename, creating the
dictionary if absent); DWG round-trip verified.
- Toolbar New / Copy / Delete | Set current / Preview / Print. Selecting
a row loads it into the editor; Set current writes to the active
layout. Copy duplicates a layout or a setup into a new named setup;
Delete/Rename apply only to named setups.
- Scene::plot_settings_for(name) generalizes effective_plot_settings so
any layout's settings can be loaded; on open the settings are
snapshotted for <previous>.
- Default selection: model space → <none>; a layout → its own setup.

Break up the four giant files (~29k lines total) into focused submodule
directories, one concern per file. Pure mechanical moves — behavior is
unchanged.
- app/update.rs (9650) -> app/update/{mod,viewport,command,style,file,
dynamic,dialog,util}. The 384-arm update_inner match stays in mod.rs
with thin delegating arms; the 66 fattest arm bodies move to topic
methods. Arm set preserved exactly (384 -> 384).
- scene/mod.rs (9017) -> scene/{mod,entity,tess,hittest,layout,paper,
mspace,project,selection,modify,group_layer,preview}. The impl Scene
body is split across files via inherent-impl-per-file; struct, ctor,
fields and load-time helpers stay in the root. fn count 123 -> 123.
- app/commands.rs (6082) -> app/commands/* grouped by command family.
The 233-arm dispatch match becomes source-ordered per-family
dispatch_* handlers, preserving first-match precedence (233 -> 233).
- app/view.rs (4686) -> app/view/{mod,overlay,modal,viewcube,controls}.
Largest file drops from 9650 to 3343. Builds clean; app launches and
loads plugins with no panic.
