If there were two inputs sending styles to the same target (ie row and column gap), they would override each other.
This change fixes that by deepening the merges. Admittedly, I turned to cGPT to help me with this as the nesting was throwing me for a loop. It works, though, and I understand it now that I can read it.
defaultValue matches the normal styled values of the gap property on the .pages element.
removed the "tooltip" that showed the current value from the range sliders inside the anchoredbox (the gap sliders).
Rather than a single button with three states, it is three buttons. Went with buttons with `role='radio'` rather than true radios mostly because that is what Radix does.
Adds a new AnchoredBox component that is functionally a clone of the "saving error" notifications, but drops a lot of the JS in favor of the new (chrome-only!) CSS Anchor Positioning API. In subsequent commits, either alternate styling or a polyfill will be added non-supported browsers.
The box contains a few inputs that modify the CSS applied to `.pages`, most critically a "start on right" toggle for the Facing Pages mode.
The range slider should only display a tooltip for the value if the value attribute exists. For example, the difference between controlled and uncontrolled inputs.
Update toolBar.less
Adding class name so that it can be toggled between 'recto' and 'verso'. Verso being the normal left/right configuration, no styling is needed. With recto, the first page is shifted to the second slot, or right side.
Adding the margin resets back in because otherwise each .page margin is set to "auto" on the sides, and that makes them zoom awkwardly when in facing and flow modes.
