/**
 * BNS Data Games - thin layer over stock Bootstrap 5.
 *
 * Shares the palette and the navbar/footer treatment of the sibling tools site
 * so the two read as one family, then adds what an arcade needs and a utility
 * site does not: a dark monospaced "screen" for the text playfield, an on-screen
 * control pad for touch devices, and the game/score card grids.
 *
 * No webfont is loaded - the UI uses the system stack and the playfield uses the
 * system monospace stack, which keeps a game page fast on a phone and makes the
 * ASCII grid render in whatever fixed-width face the device already has.
 *
 * Only plain hyphens are used in this file, never an em dash, per house style.
