Apple II HGR2 Grid - Svelte Version

This is a simple little page that superimposes a 280x192 grid (the Apple II's HGR2 pixel dimensions) on top of an uploaded image, and a tooltip in each grid area that provides its X,Y co-ordinates on hover. You can toggle the visibility of the grid.

Users should resize images prior to upload to match the graphics mode's 7:5 aspect ratio.

Either clone this and run it locally, or visit https://a2-hgr-grid.netlify.app/.
