The bulk-action bar (the purple-tinted row that appears between the
VOD filter and the grid when 1+ VOD checkbox is ticked) was 100%
inline-styled in HTML, which meant:
- No animation when it appears — it just popped into existence
- No reusable styling for similar action surfaces later
- Layout debugging meant editing HTML, not CSS
Extracted to a proper .vod-bulk-bar class, plus .vod-bulk-count for
the "N selected" label and a .vod-bulk-spacer for the flex push.
The CSS rule also picks up a 4px soft purple shadow + a slightly
richer gradient background that matches the rest of the purple
surfaces in the app.
Animation: vod-bulk-bar-slide @keyframes fires every time the JS
flips display:none -> display:flex, because @keyframes restart on
each display change. 220ms, cubic-bezier(0.16, 1, 0.3, 1) for a
quick spring landing, 10px translateY-from + opacity 0->1. The
appear feels intentional now instead of jarring.
Disappear (display:flex -> none) still snaps because CSS cannot
transition through display:none — adding that would require a
class-toggle refactor and an explicit timer to defer the actual
removal. Not worth the complexity for the polish-grade improvement
this is going for.
