- Updated the LCD UI to reflect the new button layout, ensuring the on-device display stays in sync with the revised hardware interaction model.

- Reworked the synthesis feature so that it now pulls context from relevant apps rather than only the current active app. This is a meaningful improvement to the core value of SPARK — the system can now produce more complete and useful summaries by considering the broader set of open context, not just whatever window happens to be in focus at the moment of the keypress.

- Next up: making the response drafting feature smarter, with improvements planned for next week.
