The run's paper trail — nine changelog entries and the README catches up

README: the lane header's chrome loses its + and gains the collapse story,
card faces gain chips and the hero banner, keyboard navigation gains the
sticky row, the clipboard bullet gains Copy Link, the symbol grid becomes
three per-level shelves, and Printing gets the bullet it never had.
CHANGELOG: everything user-facing since the last documented commit, the
print feature and its entitlement fix folded into one honest entry.

 **August 2026**
 
+Boards, lanes, and cards now each pick from their own curated symbol shelf in the style editor.
+
+Card faces now wear quiet chips for comments and attachments when a card has them.
+
+A card can now carry a hero image — name one of its attachments under a *hero:* key and it banners across the face.
+
+File ▸ Print (⌘P) prints the board as a flowing document — or one card from its window — with configurable content, page breaks, and named print profiles.
+
+Arrowing across lanes now remembers your row, so passing through a short lane and back returns to the card you left.
+
+The lane header's + button is gone — new cards come from ⌘N, Return on a selected lane, or double-clicking empty lane space.
+
+Copy Link on a card's context menu puts the card folder's location on the clipboard.
+
+Lanes now collapse to a slim titled strip — fold with the header's chevron, expand with a click on the strip.
+
+New boards on Mac and iPhone now start with the current agent guide, and the phone refreshes an outdated one when a board opens.
+
 Dragging a lane's edge past the screen now keeps widening the lane by narrowing the others, instead of stopping — so wide lanes work even in full screen.
 
 Edit ▸ Undo, ⌘Z, and the toolbar's Undo and Redo buttons now work on board changes — they had been silently disabled.
