Mission Control Timeline — T-Minus Event Log with Status Dots

Launch-console aesthetics with dashboard discipline: a T-minus/T-plus event sequence in strict monospace, GO/HOLD/NO-GO status lights paired with text labels, a phosphor-green 'now' cursor line, and scan-line texture — the high-contrast technical idiom for aerospace dashboards, infra monitoring and countdown pages.

## JavaScript
```js
/* No JavaScript — column alignment is guaranteed by monospace ch grid tracks; status is triple-encoded (color, shape, text) so nothing depends on the blink or the hue. */
```

How this works

The grid is fixed-track: grid-template-columns: 9ch 14px 1fr 8ch (T-time · light · event · station) repeated per row — ch units in a monospace stack mean the columns are ALIGNED BY THE FONT, the way real consoles are. T-times are signed (T−00:12:00 / T+00:02:14) with true minus signs, right-aligned, tabular.

Status is triple-encoded: the light's color, its shape treatment (steady vs blinking vs hollow), AND a text label in the station column — GO / HOLD / NO-GO survive grayscale, color-blindness and screen readers. The HOLD light blinks with a steps(1) opacity keyframe (a hard console blink, not a soft pulse) — and blinking stops under reduced motion, where the hollow/steady/filled shapes still differentiate states.

The 'now' line is a row-spanning element between past and future events: a 1px phosphor rule with a ◄ NOW tag. Past rows dim with opacity; future rows sit full-strength below it — time reads instantly without a single date being parsed. Scan-lines are a body-wide repeating-linear-gradient at 3% alpha; texture, not information.

Techniques used: monospace ch-track grid (font-guaranteed column alignment) · triple-encoded status (color + shape + text) · steps(1) hard blink gated by reduced-motion · past/future dimming split by a 'now' divider row · repeating-linear-gradient scan-line texture · signed tabular T-times with true minus glyphs

Make it yours

  • Feed it live: each row is static markup a template loop renders; move the NOW divider by rendering it between the right rows.
  • Phosphor hue: the --tl-go token — classic green, amber (P3 phosphor) or ice-blue all read 'console'.
  • Blink cadence: the 1s steps(1) keyframe on HOLD lights; real consoles blink 0.8–1.2s.
  • Scan-line intensity: the .03 alpha — keep it under .05 or text contrast suffers.

Gotchas — read before shipping

  • Use U+2212 (−) for T-minus, not a hyphen — hyphens are narrower than digits even in some monospace fonts and break the column rhythm.
  • Blinking content must stop within 5 seconds OR be pausable per WCAG 2.2.2 — here it's state-scoped (only HOLD rows) and killed under reduced-motion; don't blink whole rows.
  • Don't dim past rows below ~0.55 opacity — dim-but-present must still pass 4.5:1 for the smallest text.
  • Scan-lines over text are texture: keep them on a pseudo-element with pointer-events:none so selection and clicks pass through.

Floor set by color-mix() as this demo is written. The core technique itself goes back further — Chrome all.

Monospace grid tracks, steps() keyframes and gradient texture are baseline-everywhere. Nothing gated.
