    Post-Specific Banners - Convert highlight boxes to sidebar banners
    Author: Brian Katzung <briank@kappacs.com>

    Paste this banner manager in a custom code block above post content.
    Put your (optionally linked) banner images in highlight boxes.
    Use box title ##banner@position for single sidebar or
    ##lbanner@position or ##rbanner@position for left/right sidebars.
    Positive positions from start (0 first), negative from end (-1 last).
    Multiple positions may look similar due to hidden sidebar content.
