/* nes-mapper-inspector.css: styles for R-Z5.5.W-EXTRA-MAPPERS.
 *
 * Houses the .va-cog-nes-mapper-* token namespace used by the SPK-101
 * wk-6 Panel G cartridge / mapper inspector (status row + 2-column
 * body with PRG + CHR bank layouts on the left, decoded mapper-
 * specific registers + last-write event on the right). Lives in a
 * separate file (NOT portal.css, NOT nes-debugger.css) per the
 * scoped-CSS-file pattern (now NINE-vouched: portal-toc +
 * six-oh-two-illegal + nes20-extension + tilemap-palette +
 * nes-debugger + nes-save-state + nes-apu-inspector +
 * nes-sprite-inspector + this file).
 *
 * Mobile-first per Z5.1 L1. Bank-switch animation uses a fade-out
 * keyframe applied to data-flash cells; the wrapper sets data-flash
 * for ~12 frames after a cartridge-space write (~200ms at 60 fps).
