/* site.css — python-visuals.com's shared layer: the menu, the footer, the falling sky's canvas, and the design language
   carried across every page (captain, 2026-09-16 evening: "make sure the design language is carried across the entire site
   … make sure that the nav bar is consistent"; menu + footer everywhere; the papers keep their own reading page).
   Extracted once (9/16 evening) from the home template's own CSS — the chrome rules verbatim, class names mapped to pv-*
   and tokens to --pv-*, so no page's own classes or tokens can collide with them — and edited HERE as the source since.
   Loaded after each page's own <style>, so on an equal footing the shared layer wins. */
