 # Plan: Project table card with a QR code

 ## Notes
 
+- Defaults taken on the two open questions in #232, recorded as the
+  spec's local principles: the code points at the project page rather
+  than joining on arrival, and anyone can print a card.
+- Print scales the card up (4" code, larger title) so it fills a Letter
+  page; on screen it stays a 3" preview.
+- The code encodes `window.location.origin`, so a card printed from a
+  test instance points at that instance.
+- A real phone scan of a paper card is left to the first hack night;
+  the decode check covers the encoded URL.

 ## Follow-ups
