/* RISCON Labs — Field skin (2026-09-26, Claude)
 *
 * Reference: Kunumi Institute (kunuminst.org), Awwwards Honorable Mention 2026-04-02.
 * Taken as principles only: the first screen is a field of points; one glass prompt is also
 * the menu; the same material can be seen as a field, an index of cards, or a single line;
 * small, quiet type with mono tags. No code, images, marks or wording come from the reference.
 * Korean is set in Pretendard (no serif). Each size has its own tracking and line height.
