/* ==========================================================================
   RETROFUTURISM — loaded on a/retrofuturism.html only. Class namespace rf-.

   Ported from the approved prototype (Claude Pro, 2026-09-26); the art
   direction is frozen. Every value below is this page's art direction, not
   Retrofuturism canon: the record establishes no palette and no typeface, and
   the downloads carry none of this (claim-register.ts guards every export).

   The apparatus is a neutral grey-green instrument for viewing obsolete
   futures; only specimens take on a period's look. Time is two hues:
   --rf-past (oxblood) and --rf-future (ultramarine).

   FONTS, self-hosted, all OFL, no new files: Barlow Condensed (500/600) and
   Newsreader for the apparatus; the four period specimens use Poiret One,
   Michroma (fonts/pv), Big Shoulders Stencil (standing in for the
   prototype's Saira Stencil One: same stencilled-industrial role, already
   bundled) and VT323. Poiret One is a hairline face: below display size the
   1930s component translations set in Josefin Sans, a geometric companion
   that keeps the period's uppercase and tracking and stays legible.
