 * aspect ratio makes it quite short (~220px tall at 390px wide) — too
 * short for the HUD + build panel to overlay on top of the canvas without
 * clipping or crowding (this project's own screenshot review caught
 * exactly that in an earlier round). Rather than distorting the game art
 * to fill a taller box, the canvas keeps its correct 16:9 proportions and
 * the HUD/build panel move into normal document flow BELOW it, so the
 * whole page simply grows taller and everything stays legible — matching
 * the user's own suggested fix. Landscape (phone rotated) and desktop are
 * completely unaffected: the canvas overlay layout above is unchanged
 * there. Only the persistent icon row (fullscreen/sound/music) stays
 * overlaid on the canvas corner in both orientations, switching to a
 * vertical stack in portrait since there's no longer a horizontal HUD
 * row sharing that corner to reserve space against. */
