v1.1.0

Added

• Docs navigation — click .md links to navigate in-window with
  back/forward history (⌘[ / ⌘]), a sidebar file tree, [[wiki-links]]
  resolved across the workspace, and a workspace-wide full-text search palette
  (⇧⌘O). File ▸ Open Folder as Workspace… sets the root explicitly.
• Preferences window (⌘,) — override the theme (System/Light/Dark), accent
  color, and base font size, and load a custom CSS file (Settings scene).
• Window pinning — Window-menu commands: Float on Top (⌥⌘P), Visible on All
  Spaces, Move to Active Space, and a Ghost Mode that dims the window until you
  hover or hold a modifier.
• Rendering polish — copy-code buttons and language badges on code blocks,
  heading anchor links, and a live word-count pill.
• Export PDF… (⇧⌘E) — write the rendered document straight to a PDF,
  alongside the existing Export Standalone HTML.
• Commercial / Team license materials (COMMERCIAL.md,
  docs/commercial-agreement-template.md).

Changed

• Print / Save as PDF now uses a print-tuned @media print stylesheet
  (forced light palette, page-break avoidance for code/tables/diagrams, printed
  link URLs) for cleaner pagination.
• Find in preview is reimplemented as a JS-owned engine using the CSS Custom
  Highlight API — no DOM mutation, so highlights never leak into Export/Print.
• fetch-vendor.sh now verifies every downloaded library against a pinned
  SHA-256 manifest (scripts/vendor.sha256) and fails on mismatch.

Removed

• The "Stay Visible in Full Screen" pinning option — unachievable for Markee's
  activating DocumentGroup windows.

Fixed

• Mermaid and KaTeX render failures now surface in the in-app error banner
  instead of failing silently.
