   DRISHYA SIDS — Speed Indication Display System
   ─────────────────────────────────────────────────────────
   Rides on the shared brand system (Manrope, #43AF43, pill
   buttons, --content-ease, the reveal + counter scripts) and
   reuses Angad's primitives (.ag-head / .ag-approach / .ag-mission /
   .ag-closing) + the About shells (.ab-do / .ab-card).

   SIDS'S OWN IDENTITY — THE LIVE DISPLAY.
   The product IS a roadside sign that shows a driver their own speed,
   and the whole pitch is psychological: awareness produces voluntary
   compliance. So rather than describe that in a card grid, the page
   RUNS one — the speed climbs, the sign goes red and flashes SLOW
   DOWN, the driver eases off, it turns green and says THANK YOU.
   New components are prefixed `sd-`.

   HERO
   Nothing to override any more:

   • Height is handled site-wide in style.css — calc(100vh - 85px), so the
     hero subtracts the navbar it is margined clear of.
   • The earlier banner carried its own feature strip (Real-time Speed
     Detection, Multi Lane Monitoring, …) baked along its bottom edge, which
     needed `object-position: center bottom` to survive the object-fit crop,
     plus extra bottom padding to lift the copy clear of it. THE FINAL BANNER
     HAS NO SUCH STRIP — so both of those are gone, and the crop centres and
     the copy sits exactly like every other hero on the site.

   The one thing that must stay: <picture> is display:inline by default, which
   collapses the height:100% on .slide-img inside it — the banner then measures
   zero and never paints.
