/*
 * Abhyas full-page preloader.
 *
 * Design intent: reuse the logo's own construction (pixel grid, amber crossbar)
 * so the loader reads as the brand "assembling" rather than a generic spinner.
 * All motion uses steps() timing on purpose: stepped easing keeps the retro-pixel
 * language consistent and avoids smooth tweens that would clash with the mark.
