/* The landing page's look, from the draft landing-v21-2026-10-14/style.css with every selector scoped to
   body.landing-page, since every page links each stylesheet under app/assets. The draft's own note:
   Accelor.AI landing v21 (draft, not deployed). Look and feel taken from landing-v20-2025-12-10/v20-final.html:
   same tokens, Inter, red #cc0000, light/dark by [data-theme]. Removed from v20: cookie banner, testimonials,
   social icons. Added: screenshot placeholders, the plan card in the chat illustration, pricing notes. */
