/* AI Insights Bangladesh — aiinsightsbd.com
   Layout: phone-first. Full-width colour bands (violet hero, ink strip, lilac band, ink footer),
   each with a 1120px inner wrapper; reading pages use a 760px column.
   Brand: violet is the biggest colour, lime is the AI spark, orange appears once per page.
   Sticker look (3px ink line + 6px hard shadow) is kept to at most three items per page;
   cards are flat and only lift on hover. No gradients. */
