/*
  Apto landing page (D-255).

  Colours, radii and the hero gradient come from lib/core/theme/tokens.dart,
  and the token names match the published legal pages (D-245) so the site and
  the documents read as one product.

  Layout uses logical properties only (padding-inline, inset-inline, start /
  end) — the same RTL-readiness rule the app follows (CLAUDE.md), so Arabic
  costs a translation file and nothing else.
