/* StarCraft: Ashfall — enhancement layer styles
 *
 * LAYOUT CONTRACT: the base game locks the document with `overflow: hidden`
 * and positions its deployment controls in normal flow down the left side.
 * Measured at 1440x900, the "部署小队" button sits at x 45-469 / y 565-637.
 * An earlier build docked this drawer on the LEFT, where its panel covered that
 * button and made the game unstartable (elementFromPoint returned the panel, so
 * the click never landed). So: dock to the RIGHT, stay position:fixed, and
 * never join the document flow.
