+//! Figma HTML clipboard parsing — ports `pen-figma/figma-clipboard.ts`.
+//!
+//! Figma's Cmd+C-on-canvas writes an HTML clipboard payload that wraps
+//! a base64-encoded `.fig`-kiwi binary buffer + a JSON meta blob in
+//! HTML comments / data-attributes. This module decodes that payload
+//! into a flat `Vec<PenNode>` matching TS `figmaClipboardToNodes` —
+//! including the post-process steps that swap unresolvable
+//! `__blob:` / `__hash:` references for grey placeholder fills and
+//! enrich text nodes with inline CSS hints recovered from the HTML.
+//!
+//! The `.fig.json` clipboard format (JSON wrapper, distinct from this
+//! HTML format) lives in `lib.rs::extract_clipboard_nodes` and is
+//! unrelated.
+//!
+//! Host integration: a desktop paste handler can call
+//! [`is_figma_clipboard_html`] on the system clipboard's HTML payload,
+//! then [`figma_clipboard_to_nodes`] to obtain insertable PenNodes.

+# entries (CFBundleName / CFBundleIdentifier / CFBundleIconFile come
+# out blank or set to the package name, Resources/ is never created,
+# and the UTI-based file-association keys aren't emitted at all). On
+# macOS 10.10+ the document-binding lookup is UTI-based (.fig files

+# an `UTImportedTypeDeclarations` claim the OS will not route .fig
+# double-clicks to our bundle even if `CFBundleTypeExtensions`
+# contains "fig".
+#
+# This script:
+#   1. Builds the release binary.
+#   2. Runs cargo-bundle.
+#   3. Renames the produced `.app` to `OpenPencil.app`.
+#   4. Backfills the Info.plist with CFBundleName / CFBundleIdentifier
+#      / CFBundleIconFile / CFBundleShortVersionString /
+#      CFBundleDocumentTypes (with UTI binding) /
+#      UTImportedTypeDeclarations.
+#   5. Copies the icon into Resources/.
