/* Three-step hero animation.
 *
 * Stage A (0–33%): camera frame + shutter flash, image lands.
 * Stage B (33–66%): redaction rectangles fade in over the image.
 * Stage C (66–100%): chat bubble appears, AI markdown lines reveal top-down.
 *
 * Pure CSS keyframes. SVGs inline in the HTML. Respects reduced-motion. */
