/* ==========================================================================
   RedFamosa - product manual stylesheet
   Self-contained: no CDN, no web fonts, no external assets.
   Opens straight from disk (file://) with a double click.

   Layout ...... fixed sidebar + single scrolling column
   Accent ...... #6d3bf5 (RF_BRAND_PRIMARY), used sparingly
   Rules ....... no decorative shadows; separation by space, hairline and
                 colour; light type weights for headings; every table and
                 code block scrolls inside its own box so the page itself
                 never scrolls sideways.
