/* ============================================================================
   aoe-terminal.css — Age of Eons "FIELD-TERMINAL" design system.

   A naturalist field-journal TERMINAL aesthetic: near-black backgrounds,
   phosphor-green phosphor text, amber code highlights, monospace type,
   corner-bracket panel frames, a left "spine" rail, mono stat tiles, and a
   faint scanline / grid CRT texture.

   HARD CONSTRAINTS (do not break):
     - Fully static + CSP-safe. ZERO external loads: no CDN, no web fonts,
       no external scripts/images. System monospace only. Inline SVG glyphs
       live in the HTML, never fetched.
     - Driven entirely by CSS custom properties on :root. Themeable via a
       [data-theme] attribute; ships ONE strong default (field-terminal).

   Token contract (every theme implements these):
     --bg / --bg-inset / --panel / --panel-2   surfaces
     --edge / --edge-bright                     hairline + phosphor borders
     --ink / --ink-bright / --ink-dim / --ink-faint   text ramp
     --accent (phosphor)  --accent-2 (amber code)
     --grid  --scanline   background textures
     --mono               monospace font stack
