   FORGE — shared framework stylesheet
   Loaded with an ABSOLUTE path (/assets/global.css) on every page, at any
   folder depth, so it never breaks when a tool lives at /tools/x/y/.
   This file owns: reset, tokens, header/nav, footer, ad slots, buttons,
   the tool grid, and the shared "page-intro" header block. Anything a
   single tool needs that no other page needs belongs in that tool's own
   style.css instead.

   Forge's palette is soot and hot metal: a warm near-black (not blue-black)

   single flat "AI orange" — an actual four-stop molten gradient that runs
   from white-hot yellow through orange into cooling ember red. The
   gradient is reserved for a few deliberate spots (the mark, the equals
   key, the hero glow); everything else stays quiet steel and soot. */
