/* Abyss mine (深渊矿洞) site. Palette: dark rock base, warm lantern light as the accent, four ore colours that only ever mean rarity.
   Type matches the X images: brush script (Ma Shan Zheng) for headings, Song serif for text, Cinzel for numbers and Latin labels,
   and a red seal as the brand mark. No heavy sans headings or pixel/mono display type (those belong to Amber). */
