   FILE: website/assets/seo.css
   PURPOSE: SEO-385 page kit — the shared styles for the keyword landing pages
            (/restaurant-billing-software/ … /captain-app/, /petpooja-alternative/)
            and the public Tadka Academy (/academy/), linked as /assets/seo.css?v=385
            AFTER /assets/site.css.
   MODULE: Marketing website (website/) — Plan 385 WS2 + WS3
   LAYER:  Stylesheet
   DEPENDENCIES: - /assets/site.css — every var(--…) token used here is defined there
   EXPOSES: - .seo-* classes (hero answer, video facade, chips, cards, checklist rows,
              steps/offer, FAQ, guide layout + chapter rail, groups, floating WhatsApp)
   BUSINESS CONTEXT: one stylesheet for every SEO page so the landing pages and the
            generated Academy pages look the same and re-skin from site.css tokens.
   SOURCE: extracted VERBATIM from the <style> block that is identical in the four
            approved mockups sitemap/Mockups/website-redesign-dark/{s-385-restaurant-
            billing-software, s-385-switch-from-petpooja, a-385-academy-guide,
            a-385-academy-index}.html. Keep every class name — the Academy generator
            (scripts/seo/build_academy_pages.py) emits them. Tokens only, no colour literals.
   CHANGE LOG:
     [2026-10-04 13:00] Claude — Initial creation (Plan 385 WS2 port).

/* ══ SEO-385 PAGE KIT ═══════════════════════════════════════════════════════════
   The SAME block sits in all four Plan 385 mockups (a-385-academy-guide, a-385-academy-index,
   s-385-restaurant-billing-software, s-385-switch-from-petpooja). On port it becomes ONE
   shared file, website/assets/seo.css, linked by every SEO page — never four copies.
   Colours: var(--…) tokens from website/assets/site.css only, no literals.
