load_config synchronously parsed every recent DWG's embedded preview
on the main thread before the first frame, so the Start page appeared
seconds late on DWG-heavy recents. refresh_recent_thumbs now decodes
the missing previews on a background thread and delivers them via
RecentThumbsLoaded; the page opens immediately and thumbnails pop in
as they resolve. The web build (no threads, no filesystem previews)
skips the fetch.

Generate a small wire-raster thumbnail when saving a DWG and embed it via
acadrust's preview API, so OCS drawings show a thumbnail in file browsers
and other CAD applications. Read the embedded preview back cheaply (file
header + preview bytes only, no full parse) to show a thumbnail per file
in the Start page's Recent Documents panel.
- io/thumbnail.rs: CPU rasterizer (current-layout wires -> BMP DIB) plus
a preview-only reader/decoder (BMP/PNG -> iced handle) for the Start
page.
- Embedded on save via stamp_thumbnail on both save paths.
- recent_thumbs cache filled on config load / recents change (never from
a view); a thumbnail is drawn beside each recent file.
Requires acadrust at 3111694 (preview read/write), already pinned in
Cargo.lock.

App preferences were spread across six flat plain-text files (settings.txt,
recent.txt, recent_limit.txt, statusbar.txt, ribbon.txt, plot.txt), each with a
bespoke line parser and no grouping. Replace them with a single grouped JSON,
serialized via serde (enabling the derive feature; serde_json was already a
dependency).
- New app/config.rs: AppConfig { settings, recent, statusbar, ribbon, plot } →
<config>/settings.json (pretty JSON), load()/save().
- Make UserSettings, StatusBarConfig/StatusPill, CollapseMode and
PlotDialogState serde-derived; #[serde(skip)] marks the plot dialog's runtime
fields so only print preferences persist. Their bespoke .txt load/save is
removed.
- App gains current_config/apply_config/save_config: one AppConfig::load at
startup distributes into live state; every settings-change site
(persist_settings_if_changed, recent add/remove/limit, status-bar pill
toggle, ribbon density, plot commit) routes through save_config, which diffs
against the last write to avoid thrashing.
- Clean start: the old flat files are ignored (no migration). ocad.pgp stays a
separate hand-editable file.

Ribbon:
- A ▾ selector at the right of the tab row picks the tool-panel density —
Auto (size to window), Full, Compact, or Collapsed. The choice is persisted.
It hides itself when the tool row is already tight, giving the cramped tab
row its space back.
Start page:
- The Recent Documents card is restyled to match the Supporters card
(rounded corners, 20px padding, matching title + colours).
- Its scrollbar no longer sits on top of the row ✕ remove buttons (a gutter
is reserved).
- A footer control sets how many recent files to keep: [-] an editable count
[+] with the max shown. Typing applies on Enter; an over-max entry snaps to
the max. The limit is persisted and enforced on load and on every open.
- The "Support on Patreon" heart is now the SVG icon instead of a font glyph.
Config:
- Add a shared `config::config_dir()` helper; the recent-files and status-bar
stores now go through it instead of each re-deriving the path. New minus.svg
icon for the stepper.

Remove the OCS-logo button and the dropdown menu it opened; the top strip
now shows direct New / Open / Save / Save As / Print buttons ahead of the
undo/redo controls. Drop the HELP and OPTIONS commands (HELP dumped text to
the command line, OPTIONS aliased the drafting-settings popup).
The app-menu overlay is gone, so its rendering code, MENU_ITEMS, four dead
messages, and the LOGO_RED / GEAR / HELP assets are removed. The recents
list it held is the only survivor — moved into OpenCADStudio.recent_files
via a new app/recent.rs, backing the Start page's Recent Documents panel.
Quick-access icons are redrawn in a cleaner style (file-plus, folder-open,
device-floppy, file-export, printer) and tinted light so they read on the
dark strip; FOLDER / DOC keep their old glyphs for the file browser.
