/* Listening — journal.algernonlabs.com
   Layout and components ported from the Claude Design mockup
   (Landing.dc.html / Support.dc.html).

   The palette is NOT defined here. app/theme/tokens.ts is the single source of
   truth for colour, and the custom property names below mirror its keys exactly
   (ink900 -> --ink-900, accentSoft -> --accent-soft) so one name means one value
   in both the app and the site. `make check-site` fails if they drift.
   Add a colour to tokens.ts first, then mirror it here. */
