Every room from the top of the page

The navigation is on every page now, not just the zone, and it is two rows. Here, Character and Travel across the top; underneath, when there is anything to walk into, the place you are standing and its rooms — Lucerna, Vendor, Bank, Auction, Mailbox.

That replaces the "Back to Lucerna" links at the foot of each building and the "Visit the bank" links buried in the zone panel. Both did what the bar does, only further down the page. The zone names its own tab because there is no word for the screen you were already on: you are in Lucerna, or in Lucerna's bank.

A craft with nowhere to put its output is refused before it starts. Materials and the workbench fee were taken when the work began and the item arrived when it finished, so a full bag at the end meant paying for something nobody received. Buying and withdrawing already refused; crafting does now too. What counts is the room free once the ingredients are out, so it only bites when they come from a stack deep enough to survive being eaten.
