/* Skirmish II play page — AoE2-style interface layout + painterly chrome.
 *
 * Functional organization in the classic RTS pattern: a resource bar
 * across the TOP, a contextual COMMAND PANEL bottom-left, a SELECTION
 * PANEL bottom-center, and a MINIMAP bottom-right. The layout idea is
 * the genre-standard one; every visual is ours — original generated
 * art (ui-art/: walnut wood and parchment textures, a carved medallion
 * frame, and the painterly icon set v2) in a warm walnut / aged-gold /
 * parchment scheme. Nothing is copied from any other game.
 *
 * Loaded AFTER play.css. Everything is namespaced under .ui-* /
 * .cmd-* / .sel-* / .res-* so it cannot collide with other rules. */
