lib-theme-flint: initial import (calm-pro/dense-utility set, 2026-07)

One of four divergent candidates for the operator/console theme family
(successor to Skyrise for developer-product screens). Dense/pro type
register, keyboard-first focus treatment, tabular numerals, coarse-pointer
44px touch floor, neutral code chips, dark card separation per house sweep.

+# lib-theme-flint
+
+**Flint — instrument panel.** Braun/Dieter-Rams workshop calm with one signal spark: a warm-stone
+gray field, white cards, graphite-umber ink, and a single signal-orange accent — the machine's
+indicator lamp — spent only on the primary action, selection, focus, and the live dot. Dark mode is
+the panel at night: dark warm graphite (never blue) with the orange glowing luminous under dark ink.
+Dense/pro register, machined 0.625rem radius, crisp low shadows, mechanical-quick motion
+(120/220/320/450ms, springs aliased — a good tool clicks, it doesn't bounce). Built for
+operator/console/admin surfaces.
+
+## Fonts
+
+Themes never `@import` fonts (PostCSS ordering). The **consuming app** loads them at the very top of
+its entry CSS (`app/app.css`):
+
+```css
+@import url("https://fonts.googleapis.com/css2?family=Archivo:wght@400;500;600;700&family=Inter:wght@400;500;600;700&family=JetBrains+Mono:wght@400;500;600&display=swap");
+```
+
+| Role | Stack |
+|---|---|
+| Headings (`--font-heading`) | Archivo → Inter → system sans. Grotesk with DIN-instrument character; headings render at weight 600. |
+| Body (`--font-sans`) | Inter → system sans. Body 0.9375rem / 1.5. |
+| Code (`--font-mono`) | JetBrains Mono → ui-monospace → SF Mono → Menlo → Consolas. |
+
+Notes: tables (`[data-slot="table"]`) and the `.num` utility class get `font-variant-numeric:
+tabular-nums` — instrument readouts demand aligned digits. Keyboard-first focus is a signature:
+buttons get an always-visible 2px signal-orange outline (2px offset); inputs a flush 1px ring +
+border-color change.
