/* === MATRIX "INFECTED" GLITCH LAYER ===
   Subtle by default — does NOT disturb reading. An occasional, brief screen
   "crack" reveals green katakana digit-rain (painted on #matrixCanvas by
   matrix.js), with light scanlines + RGB-split for a "virus" feel. Hovering
   the hero name or the Agent Smith card raises the glitch rate.
   All colours come from the --matrix-* tokens in base.css (no hardcoding).
   Pure CSS + one throttled canvas → negligible cost; canvas only paints
   during a glitch burst. Respects prefers-reduced-motion. */

/* Digit-rain canvas — full screen, above content but click-through. Now
   ALWAYS painting a faint Matrix rain in one corner (the page is permanently
   "infected"); during a glitch burst it additionally paints jagged cracks
