I like it!

Demo bugs:

- Clicking on the header of the static data table brings up an alert box saying 'testing'

- Clicking Render Modal Matrix Modes brings up a modal that's too tall to see the close button (Chrome, Win11, screen res 1920x1200, display scale 125%, viewport 1536 x 826)

Toolkit bugs:

- If a modal is active, the background should be dimmed. This is implemented for other modals (opening one modal on top of another will blur the bottom modal attractively) but not for the base page

- Clicking outside a modal should probably dismiss it by default, although this does need to be able to be disabled
