/* Central Drive Hub - the central-drive site's system: near-black ground, square edges,
   white-hairline panels, Barlow Condensed display type in caps, Inter for reading,
   silver primary buttons, a soft sky-blue accent used sparingly.
   Layout: brand rail + content column; a top bar with a scrolling tab strip on phones.
   One dark theme, on purpose, like the site and the station app. */
