/*
|
||
* .action-btn — Square SVG icon button used in the bottom-right action toolbar.
|
||
*
|
||
* Design rationale:
|
||
* - Mirrors .icon-btn sizing (32px square) so the action toolbar is visually
|
||
* balanced with the annotation toolbar.
|
||
* - Uses `currentColor` so each instance can override its own hue (e.g. the
|
||
* primary upload button is blue) while sharing one base set of rules.
|
||
* - The native CSS tooltip is rendered through `::after` driven by the
|
||
* `data-tip` attribute. This avoids the system `title` tooltip's slow show
|
||
* delay and lets us style/position the bubble consistently.
