   Kaotom — public landing page
   Standalone on purpose: styles.css carries the app shell's layout (full-height
   grid, fixed sidebar) which a marketing page must not inherit. The token block
   below mirrors styles.css value-for-value so the two never look like different
   products; change a colour there and change it here.
   Dependency-free. Light + dark, both first-class. Thai + English in one page.
