/*
 * Game board, from the approved royal-blue and gold mockup (1448 × 1086).
 *
 * Every size is written in mockup pixels times --u, so the whole interface
 * keeps the mockup's proportions at any window size:
 *   sidebar 290 wide · logo 340 × 201 · info panel 519 tall · button panel 303
 *   board frame 22 thick, starting 75 below the top of the logo.
 * Wide screens: --u follows the window height (the sidebar fits top to bottom)
 * and the board takes all the remaining width.
 * Portrait phones: a different arrangement (see the end of this file).
 *
 * Gold frames are gradients drawn in the border box (smooth, anti-aliased
 * curves at every zoom) — no raster frame is stretched.
