   showing "C..." — 24px of width for a 44px word. Measured on all six games: five of them
   clipped, and "Junta Números" needed 112px for the 24px it had.
 *
 * THERE IS NOTHING TO GAIN BY KEEPING A ONE-LETTER CHIP. The game's name is in the page
   title, in the browser or in-app tab above the board, and on the home screen the player
   just came from. A truncated chip is not a shorter version of that information; it is a
   row of pixels that says "C".
 *
 * SO BELOW 430px THE CHIP GOES AND THE SPACE GOES TO THE CONTROLS. 430px is where the chip
 * can show a full short name with the existing sizes: seven 40px targets, six 4px gaps and
 * the padding leave about 80px, which fits "Cobra" and "Trio" but not "Junta Números". Above
 * it the chip stays, because a wider screen has room and the name is a useful orientation
 * cue.
 *
 * `sr-only` rather than `display:none` for the NAME: the heading is what a screen reader
 * announces as the game it has opened, and removing it entirely would leave that heading
 * empty. The visible chip is decoration on top of an accessible label. */
