/* Lexilog.io public site: shared foundation.

 * Canonical brand tokens, reset, page container, brand lockup, header, buttons and footer.
 * Extracted verbatim from index.html/app.html, which carried byte-identical copies of all of
 * this, and now also serves the legal/support pages so the whole site reads as one product.
 *
 * Page-specific rules stay in each page's own <style> block, which is linked AFTER this
 * file and therefore still wins on equal specificity.
