Fill Foreground Alignment
fill-align
Sets the position of the foreground video within the fill canvas. The default is center,middle — the video is centered both horizontally and vertically, which produces equal bars on opposite sides.
fill-align accepts one vertical token (top/middle/bottom) and/or one horizontal token (left/center/right), combined as a comma-separated list. Tokens are order-independent. An unspecified axis stays at its default (center horizontally, middle vertically). Applies only when fit=fill or fit=fillmax is used.
For precise percentage-based positioning, use fill-x and fill-y instead.

left | Pins the foreground to the left; blurred band appears on the right |
right | Pins the foreground to the right; blurred band appears on the left |
center,middle | Default — equal bars on all sides |
