/* deals.sidestream.ai — one screen, mobile first, no framework (design 2026-10-13 §2.2).

   The look is www.sidestream.ai's "Trade Counter" (the www repo's src/styles/global.css): warm
   paper, near-black ink, a price-tag red, hard 2px rules and offset shadows, square corners;
   Roboto Slab headings, JetBrains Mono labels, Inter body. Everything here is self-hosted, because
   the page's CSP admits no third-party style or font, and nothing is inline (no style="", no
   <style>), so the pages never lean on style-src. The fonts are the latin subsets of the
   @fontsource files www ships, licences alongside in fonts/. */
