 * Light, restrained touches layered on the stock furo theme. Furo's own palette
 * and typography are left untouched — links, headings, and body text keep the
 * theme's defaults (so visited/unvisited links stay consistent and legible in
 * both light and dark). We only tune a few things that genuinely help a
 * system-library reference: tabular figures in tables, softly-framed code and
 * diagram blocks, and a monospace stack for inline/inline-block code.
