Building multicardz - Trello reimagined with a row dimension for true 2D organization, handling any operation on 1M cards in under a second.

Showcases genx.software (declarative HTML that extends htmx's philosophy to client-side concerns). Drag-and-drop, formatting, accessibility - all via HTML attributes instead of React boilerplate. 150ms total load time, 50 divs, 1600 lines CSS, perfect Lighthouse scores.

Soft launching both late November (early availability for HN readers).

There's a monthly post for this every second Sunday. The next one is this Sunday, the 9th.
