/* ARAYASHIKI umbrella site — the company page at the domain root.
 *
 * Deliberately standalone: unlike tiengow.html, this page does NOT load
 * style.css (the game's stylesheet). The umbrella brand has to outlive
 * any one product, so it carries its own tokens and never inherits the
 * domino visuals. Product pages layer their own look underneath it.
 *
 * Palette is a quieter relative of the TienGow site's — same ink and
 * gold so the two read as one house, less felt-green warmth so the
 * umbrella doesn't look like a game page. */
