/* Terminal Heads — stylesheet.
 *
 * Palette is measured off the art, not chosen by taste: sampling 40 files gave
 * deep teal #123D43 as the dominant casing/ground, amber #A06000 on the glass,
 * bone #C0C080 on plastic, 25% near-black outline, and only 6.5% high-chroma
 * pixels — so the page stays muted office-CRT, never neon.
 *
 * Deliberate gestalt break from the sibling project on this chain (catbanker:
 * mono-everything, brass-on-navy ledger, split hero, receipt/table surfaces).
 * Here: dot-matrix display + Archivo sans body, teal desk, centre-stage hero
 * over a live monitor bank, tape ticker as the signature device.
