/* Tide guides. A thin layer over styles.css that reuses the site's own design tokens
   (--navy, --blue, --sky, --ink, --muted, --line, --paper, --canvas, --radius, --shadow)
   so these pages read as part of atmosphr.com.au rather than as a separate microsite.
   Everything is scoped under .tide-page: nothing here can reach the weather app.
   No token is redefined, so the [data-theme="contrast"] overrides in styles.css apply here too. */

   These are reading pages with no side column, so narrow the measure and centre it
