/// **The board popover's git-note detection** (12-editions.md ▸ The free tier and `.git`, ruled
/// 2026-07-27): the free tier's whole git story is one line, shown only on a board that carries an
/// inert `.git`. The seam
/// that decides *whether* to show it — `BoardGitNote.hasGitDirectory(at:)` — is a pure, read-only
/// `FileManager` check, pinned here against real bytes on disk. Everything else about the note (its
/// wording, its placement in `BoardInfoView`) is SwiftUI rendering and deliberately untested.
