• [x] Refactor poem scaling code into a separate zoomTo function that runs inside transformSticky
• [x] Test that it works for: line block line number
• [x] Test that it works for: line block span
• [x] Test that it works for: code cell line number
• [x] Add hlz option to do both highlighting and zooming.
• [x] Add .scale-to-fill class to apply a transform on an sticky whenever its active

@jimjam-slam I believe we have a refactored zooming system that does zooming via zoom-to 🪩 . This allows uses to separately use either highlight or zoom-to on code or lineblocks. If they want to invoke both, they can use the hlz attribute that, on document load, just writes out the analogous highlight and zoom-to attributes for that trigger.

I'll try to get some docs up and possibly if I have energy before tomorrow, expanding the functionality to display math blocks.
