   TAROT CLASS corporate · layout + components
   Palette and type families come from site_v4 (tokens.css). Layout and
   typographic rhythm follow a product-showcase model: centered copy, very
   large headlines, short subheads, media that owns most of each tile, and
   generous, consistent vertical rhythm.
   Rules kept: semantic tokens on dark surfaces, no overflow-x: hidden on the
   page, no 100svh, no inline style, DOM order = reading order.
