   Layout language: instrument panel — left channel rail (hairline rows with

   chrome (34px telemetry strip + 64px icon rail from site.css).
   Squared geometry, hairline frames, mono micro-labels, one signal accent.
   Every class JS renders (.f-navitem, .f-catrow, .f-post, .chip, …) keeps its
   exact name — visuals only. Shared across Index / Category / Topic.
