  hp.nodavis.com landing page. Layout follows the "phone-width column with side panels" pattern;
  colours stay Nodavis (teal, navy) so it still reads as the same company as www.nodavis.com; typefaces follow the reference LP
  (Noto Sans JP for text, Noto Serif JP 900 for section headings, Inter italic for Latin labels) at the user's request (2026-11-05).
  Written mobile-first on its own: the corporate site.css is laid out by viewport width, which breaks inside a fixed-width column.
