/* Frothy docs — "Field Manual" design system (brutalist retro-computing).
   Ported from the Claude Design project: warm manila paper, near-black ink,
   clay + phosphor-green signals, hard 2px ink rules, blunt offset block shadows,
   the mascot critter, and a layered type system (Baste B / Schibsted / Jakarta /
   JetBrains Mono). Light "paper" default + dark "terminal" theme.
   Engines kept: search.js, reference-layout.js, froth-highlight.js (tk-* classes). */
