+### N8 · Terminal command
+A nav formatted as a CLI prompt: `> studio --catalog --voice --get▮`. The "links" are command flags. The blinking cursor (`▮`) is allowed *only here* (it has purpose — signals "you'd type next"); never standalone elsewhere on the page. Reads as Vercel CLI docs landing, Charm, Mitchell Hashimoto's site.
+*Use when:* the page is a CLI tool, dev-tool docs, or carries the Terminal theme.
+*Don't confuse with:* N4 ⌘K-only (which is a palette, not a visible bar).

+```html

+</header>

+```css
+.nav-term { padding: var(--space-sm) var(--page-gutter); border-bottom: var(--rule-hair) solid var(--color-rule); }
+.nav-term__line { font-family: var(--font-outlier, ui-monospace, "JetBrains Mono", monospace); font-size: var(--text-sm); margin: 0; }
+.nav-term__line .prompt { color: var(--color-accent); padding-right: 0.4ch; }
+.nav-term__line a { color: var(--color-ink); text-decoration: underline; text-underline-offset: 2px; }
+.caret { display: inline-block; width: 1ch; animation: blink 1.05s steps(2) infinite; color: var(--color-accent); }
+@keyframes blink { 50% { opacity: 0; } }
+@media (prefers-reduced-motion: reduce) { .caret { animation: none; opacity: 1; } }
+```
+
+*Anti-pattern:* using `>` prompt vocabulary on a non-developer site (a wedding photographer's portfolio with a `> view --gallery` nav reads as set decoration). N8 belongs to genuine terminal / CLI brands only.
