What to look for

Heading. App + Split, scroll a little: "Signals" is cut off 32px under the top edge. Sticky: it slides out at the top edge like every other lens.
Jump lands behind the pane. Sticky, pane at 45%, untick scroll-padding, jump to #15: the readout should say it's hidden. Tick it again and repeat.
Focus. Same setup, Tab through cards: with scroll-padding off, focused cards can sit under the pane.
Scrollbars. Split: the card scrollbar stops at the pane. Sticky: the window's scrollbar runs the full height, next to the pane's own. Which reads better?
Resize while scrolled. Scroll to the middle, drag the pane bar up and down. Does the content jump?
Scroll-end lift. Sticky, tick "32px bottom padding", scroll to the end: the pane lifts off the window bottom (the 1c563b29 bug).
Footer. Sticky, tick footer, scroll to the end: the pane stops being pinned once the footer arrives. Acceptable, or keep it hidden?
