/* nes-sprite-inspector.css: styles for R-Z5.5.Z-SPRITE-OAM-2026-05-16.
 *
 * Houses the .va-cog-nes-sprite-* token namespace used by the SPK-101
 * wk-6 Panel F sprite OAM inspector (status row + 64-sprite hex grid
 * + per-sprite detail panel + tile preview canvas + overlay toggle).
 * Lives in a separate file (NOT portal.css, NOT nes-debugger.css)
 * per the scoped-CSS-file pattern (now OCTUPLE-vouched: portal-toc
 * + six-oh-two-illegal + nes20-extension + tilemap-palette
 * + nes-debugger + nes-save-state + nes-apu-inspector + this file).
 *
 * Mobile-first per Z5.1 L1: every interactive surface (row click,
 * overlay toggle) is exercised on BOTH Pixel 5 (chromium) AND
 * iPhone 13 (WebKit) in the round's mobile spec.
 *
 * Tap-target floors:
 *   - Sprite row buttons are dense (64 rows in one panel column);
 *     each row is 28px tall which is below the WCAG 2.5.5 floor but
 *     within the essential-density exception (same exception Z5.2
 *     applied to hex viewer byte cells). The full row width is the
 *     tap target (>= 200px wide on mobile), so the tap area is
 *     >= 200x28 even though height is below 44.
 *   - Overlay checkbox container is 44x44.
