   Smeltworks house stylesheet  —  https://smeltworks.com/smeltworks.css
   Link this ONE file and your tool matches the whole site automatically:
     <link rel="stylesheet" href="https://smeltworks.com/smeltworks.css">
   Then wrap your page in the standard shell (see resources.md). Bare elements
   (h1-h4, p, a, input, button, table, code…) are already styled — you rarely
   need custom CSS. Dark "forge" theme: cool slate + molten-amber accent.
