/* "Terminal" Theme — green-phosphor VT100.
 *
 * The site's thesis is one federal research index rendered through eras of the
 * web: 1996 GeoCities (Retro), 1990s newsprint comic (Uncanny), modern editorial
 * (Clean). This is the era before all of them — the government terminal — and it
 * doubles as the dark mode the site otherwise lacks.
 *
 * Costs nothing to ship: JetBrains Mono is already in the base font request, and
 * there are no image assets. Every rule is scoped under `body.theme-terminal`.
 *
 * Contrast: phosphor on crt is ~14:1 and amber ~10.6:1, both AAA at any size.
 * There are deliberately TWO secondary greens, because one token can't do both
 * jobs: --label (8.9:1) carries every piece of small secondary text and every
 * label glyph, while --dim (6.1:1) is reserved for the visited-link state, where
 * it has to stay visibly distinct from --phosphor to read as a state at all.
 * Brightening --dim to fix label legibility collapses that separation from
 * 2.19:1 to 1.24:1 — hence the split. --rule is borders only, never text.
