   iot-pages.css — shared styles for the /iot/ practice hub, product catalog,
   product pages and IoT services page (single-site consolidation, batches 3-5).
   Matches the visual language of css/industry-pages.css (gold #f1b621 accent,
   navy #1a1a2e) so the /iot/ section reads as one site with /industries/.
   Self-contained; loaded alongside style.css + bootstrap.
