Signature moves

extreme monochrome with single acid-pop accent

pure black #000000 and pure white with one rgb(215, 255, 0) neon yellow-green used as a single rare chromatic hit.

multi-language font system with refined micro-radius

a 5-font multi-language system (Acumin Pro Latin display + IBM Plex Sans JP body + Hiragino fallback + IBM Plex Mono / Google Sans Code chrome) on a 12-step fluid scale (10-43.2px) with a non-standard 3.6px workhorse radius.

cinematic preloader + padding-driven hover

a heavy preloader animation opens the experience and a distinctive padding-left 0.3s ease hover shifts elements, with all 0.3s ease as the workhorse transition.
