Theme Name:        SalemWire Terminal
Author:            SalemWire
Description:       Terminal presentation layer for the SalemWire newswire engine. Liquid three-to-one column wire, CRT display profiles (Blue/Green/Amber/Mono), SHARP/SOFT screen setting, boot grammar, glyph status, optional vector field and micro-sound. Requires the SalemWire Core plugin for content; renders a plain readable wire without JavaScript.

/* =====================================================================
   1. CRT DISPLAY PROFILES — render profiles, not color themes.
   Profiles change expression only: never content, order, semantics,
   accessibility or feed state (packet §9).
   Custom properties:
     --sw-bg          field (background)
     --sw-ink         primary phosphor (body/headlines)
     --sw-ink-dim     dim phosphor (meta, blurbs, rules-adjacent text)
     --sw-accent      utility/label accent
     --sw-alert       alert/failure
     --sw-rule        structural rules
     --sw-vector      vector field stroke (consumed by JS)
     --sw-glow        glow radius multiplier (SHARP/SOFT scales this)
     --sw-glow-color  glow tint
