Remove the probing-state placeholder span entirely. The chevron renders
only when playlistProbeState === 'done'; all other states (idle, probing,
error) render null. The small layout shift when the chevron appears after
probe is acceptable; blank padding while there is no chevron is not.
CaptureDialog.jsx:
- Placeholder no longer appears on idle playlist rows (only during
probing); chevron shows only after probe completes — no left-padding
while the user is still typing
- Per-video delete button added to expanded playlist list; removes item
from playlistItems so its ID is absent from per_item_quality on submit
- anyEmptyPlaylist guard: Archive button disabled + handleArchive early-
return when all videos have been deleted (empty map would otherwise
silently download everything)
styles.css:
- Selection stroke switched from outline to box-shadow:inset everywhere
(entry-row-outer, child-entry-row, legacy flat-div selector) —
guaranteed inside element bounds, no layout interference
- URL cell overflow only on :hover; removed is-selected .url-cell rule
that was expanding child URLs when their parent was selected
- Playlist items redesign: separator lines instead of background fills,
amber left-border for conflicts, thin scrollbar, tighter padding
- Remove button: opacity 0.3 always-visible baseline; full opacity on
hover/:focus-visible; forced to 1 on coarse-pointer (touch) devices
