/* ==========================================================================
   sheets-secondary.css — share, stereo, pricing, atlas, beta, why and 404.
   Linked after site.css and opal.css on those seven pages only; each carries body.sx.
   The brand (omniblick-brand, Opal with a little Celadon): porcelain, pearl and wash grounds,
   frosted white glass cards, radii 28 (cards) / 18 (panels, tiles) / 12–14 (fields, small) / 999 (pills).
   Colour lives only in the glass and the data; the drawings stay technical line drawings inside the cards.
   Both themes: light by default, dark from the nav switch (no drafting grid, no square corners).
