/*
  tty22 — design tokens
  -----------------------------------
  Color (true amber monochrome CRT — everything in one hue family,
  the way a VT220 actually looked, not green text with an amber accent):
    --bg:        #0c0904  (near-black, warm)
    --ink-dim:   #8a5a1e  (dim amber, default body text — "phosphor at rest")
    --ink:       #e8a23a  (standard amber, headers/data)
    --amber:     #ffc870  (hottest amber — active state, cursor, emphasis)
    --alert:     #b3392f  (reserved ONLY for rejection/illegal-action states
                            — the one place the monochrome breaks)
    --hairline:  #2a1d0c  (dividers)

  Type:
    JetBrains Mono throughout. This is a tty, not a brochure.

  Signature element:
    A blinking block cursor and a curved-glass CRT vignette around the whole
    viewport, with the countdown rendered like a process status line.
