polish(web): hero h1, JP cursor labels, sitemap cleanup

- promote hero title to h1, rewrite lede so the subject leads
- drop redundant 朱 paperStamp on hero canvas; masthead carries the mark
- cursor labels become 朱 / 読 / → with JP serif sizing
- sitemap drops fragment URLs (Google ignores them); remove unused
  /og/[section] route and its stale comment in layout
