/* Paper ground — proposal for owner review, 2026-10-13.
   The page stands on paper (a warm off-white); content surfaces — the live card, tables, pricing cards, the rule
   editor — on white, with the hairlines as they are. No gradients, no shadows, no texture: depth is paper vs white only.
   Loaded after the page's own stylesheet (home.css / editor.css); the roles below are the only additions. */
