/* TensorCode base: tokens, reset, the top bar, buttons and footer. Shared by the marketing pages (with site.css) and the docs (with docs.css). Palette: warm paper and deep ink, one teal accent taken from the loop in the TensorCode mark, and one coral used only for "a person corrected this". Light is the default; dark applies when the device asks for it or the visitor picks it. A one-line script in each writes data-theme before first paint. The dark palette is written twice because CSS cannot say "device asked OR visitor picked" in one rule. */ :root { --sans: "Inter", ui-sans-serif, system-ui, -apple-system, "Segoe UI", Roboto, "Helvetica Neue", Arial, sans-serif;
