Create the app icon and finalize versioning

App identity for both editions: the three-lane glyph
(rectangle.split.3x1.fill) over a gentle gradient - teal for base
Lanework, dark graphite for Lanework Pro - rendered as 1024 masters and
packaged down the full macOS ladder into each target's own iconset,
replacing the borrowed pathfinder icon.

The About window arrives via IndieAbout (0.2.x): icon, copyright,
version/build/date read from the Info.plist that update_build_info.sh
already stamps on every build (CFBundleVersion 160 = git commit count,
BuildDate, BuildHash - verified in the built product), the version line
opening the bundled CHANGELOG.md, and the new ISC LICENSE.md one
document link away. Both files are authored to the Apple
inline-Markdown subset (no # headings, single-line paragraphs) and
bundle into both editions.

CHANGELOG.md replaces its placeholder with the real 2.0 first-release
notes - one sentence per user-facing feature.

The About box is also an edition seam: base's EditionAbout carries the
one-line Pro signpost 12-editions.md allots ("Lanework Pro adds
git-backed board history and sync."), and the Pro target compiles its
own signpost-less twin instead of that file - the no-#if file-level
doctrine applied to a string. README gains the identity bullet.

1649 green on both schemes; verify-editions.sh 26/26.

 - **Accessibility** — the board is a real VoiceOver surface, not a grid of unlabelled rectangles: lanes are containers read as "⟨title⟩, lane, N cards" (the count is the filter's, like the visible badge), each card is one flattened element carrying its title, its attachment count and its cut-pending state, and traversal follows card `order` rather than masonry column position. VO-Space toggles selection through the same funnel a ⌘-click uses, context-menu rows double as custom actions, lane titles are headings for the rotor, and the trash column pins last. A **live board announces itself**: a foreign edit lands as one polite, non-interrupting digest per reload — "Board changed: 2 cards edited, 1 card added" — while the app's own writes stay silent. Which is which is decided **per file by the write-provenance ledger**, never by which kind of reload delivered it: a reconciling sweep on wake or reactivation announces whatever changed in the blind window (the app never vouches for changes it didn't witness), and a foreign edit that lands on a file the app had just written is still announced. A card that disappears under the cursor is named rather than merely lost ("Card 'Fix login' was deleted externally"), with focus recovering to its lane; when the lane went too, the announcement names the *lane* and its count and focus walks up then sideways to whatever now holds its position. Bracketed operations say one thing at completion and never their internal churn, and the banner strip is an announced element in its own right — the read-only lock and reload breakage speak when they appear and when they clear. **Every size in the app is relative**: there is not one hard-coded point size left — the card face, the lane header, the masonry, the style editor's wells and every window's floor derive from the system body font, so the whole board grows with the system text size while the no-horizontal-scroll rule holds (the lanes compress, the strip never scrolls) and titles keep truncating gracefully. The system's visual accommodations are wired throughout: **Increase Contrast** thickens every border and selection ring and gives card and lane plates an outline they don't otherwise have, **Reduce Transparency** turns the transient search bar's glass and the trash column's washes solid, and **Reduce Motion** has a variant for every animated surface in the app — movement goes instant, appear/disappear goes crossfade, uniformly, the live-reload seam included. **A coloured board computes its own text colour.** The board background is the one surface the app lets a colour sit behind text, so the ink is chosen rather than assumed: WCAG relative luminance against the ≥ 4.5:1 threshold, with an `#RRGGBBAA` value composited over the window background of the appearance you are actually in — so lane and trash headers take light or dark glyphs on their own and re-decide the moment you switch to Dark Mode. One path serves both halves of the styling vocabulary: the twelve palette wells are pinned by a test that checks the ink the app *picks* for each of them in both appearances (a dark palette board is now readable in Light Mode, which it was not), and a hand-written hex — which stays fully honoured from disk — gets the identical computation as it renders. Nothing is ever said by colour alone (selection is a ring plus a trait, a cut card is dimmed plus "cut, pending paste", the trash header is hatched plus labelled, a mixed batch reads "mixed"), and under **Full Keyboard Access** the board is a single visible tab stop with the arrow grammar inside it while every control around it — lane buttons, popovers, the style grids, welcome rows, template tiles — is Tab-reachable, arrow-navigable and labelled.
 
+- **App identity — icon, versioning, About** — each edition carries its own icon (the three-lane glyph: teal for Lanework, graphite for Lanework Pro) and a real About window: icon, copyright, version and build stamped at build time from git (`CFBundleVersion` = commit count, plus `BuildDate` and `BuildHash` in the Info.plist — never a hardcoded string), the version line opening the bundled end-user changelog, and the ISC license one link away. Base's About carries the one quiet line naming Lanework Pro; Pro's carries none, per the quiet-signposts rule (DESIGN/12).
