/* ==========================================================================
   THE ARCHIVE — screen register layer
   --------------------------------------------------------------------------
   Screen adaptations of the Never Fear print design system's component
   vocabulary (never-fear-print.css, canonical in
   NeverFearGameDesignBible/docs/print-system/). Additive layer, loaded
   after components.css — the same pattern the print system's
   lab-notebook.css uses to extend the base.

   RULES (see docs/archive-theme.md):
   · Every class here is NEW — never reuse a class name defined in
     never-fear-print.css (that vocabulary belongs to print surfaces,
     which render only inside export/preview iframes).
   · Sizes are rem/px (responsive), never mm/pt.
   · Cream (--nf-surface-well) is material — wells and callouts only.
   Each component notes its print source.
