/* The public site (Lmsqr ADR-0041). System fonts only, nothing from another origin (rule 7).
   One theme, dark and colourful (the owner's choice, 2026-10-27): a deep blue base with bands of
   colour, so the site reads apart from the app. The wordmark's blue leads; lemon, coral, mint and
   violet tint the sections. Motion is CSS only (scroll-driven animations), off for reduced motion
   and absent where the browser lacks it: the page is complete without it. */
