Build me a self hosted notes app that feels like Google Keep, but easier to use when you have a lot of notes.

I want the main screen to show sticky note style cards in a masonry grid, with a better way to browse through old notes, including month markers in the timeline, quick filters for colors and tags, saved searches, and a calendar view. It should also have a clean list view and a stacked view, plus basic folders and the ability to link notes to each other.

Please make it easy to import notes from Google Takeout, text files, and markdown files. I also want a settings area where I can change layout, background, and note behavior. If possible, include syncing notes out to markdown files so I can keep backups and edit them in another editor, and have changes come back into the app safely.

Make it work nicely on desktop and mobile, and use a simple modern setup that is easy to run locally with Docker.
