/* Tideline NZ's help: the page and its clips.

   One stylesheet for the website's help page (build-help.cs copies it to
   public_html/tideline/help/help.css) and, later, the app's Help page. Only
   colour tokens BOTH palettes define: --bg, --card, --border, --chip-bg,
   --row-bg, --text, --muted, --accent, --amber (the site's tideline/app.css
   and the app's wwwroot/css/app.css; checked 21 Oct 2026). The app has no
   --shadow-phone, hence the fallback.

   Shapes from Plotstead's Help.razor.css and HelpClip.razor.css, renamed to
   these tokens. Every :hover sits inside @media (hover: hover), the app's
   rule (RepoRulesTests). */
