lib-theme-graphite: 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-graphite
+
+**Graphite — achromatic precision.** Dieter-Rams calm for operator/console/admin
+surfaces. Every neutral is true achromatic (chroma 0) — near-white grey field,
+pure white cards, near-black ink — with ONE electric azure accent spent only on
+the primary action, links, selection, and focus. Dark mode is true dark grey
+(never blue-black) with cards stepping visibly lighter. Dense/pro type register,
+compact 0.5rem radius, product-fast motion, crisp low elevation, tabular
+numerals wired for tables.
+
+## Fonts
+
+Consuming apps must load the fonts at the very top of their entry CSS
+(`app/app.css`), before anything else — the theme file itself does not
+`@import` fonts (Crema token-contract rule):
+
+```css
+@import url("https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700&family=IBM+Plex+Mono:wght@400;500;600&display=swap");
+```
+
+### Font stacks
+
+| Token | Stack | Notes |
+|---|---|---|
+| `--font-sans` / `--body-family` | `"Inter", -apple-system, BlinkMacSystemFont, "Segoe UI", sans-serif` | body text |
+| `--font-heading` / `--heading-family` | same Inter stack | headings differentiate via weight 600 + tight tracking (−0.022em), **not** a second family |
+| `--font-mono` | `"IBM Plex Mono", ui-monospace, "SF Mono", Menlo, Consolas, monospace` | code, tabular data |
+
+## Validation
+
+```bash
+node create-crema-app/scripts/validate-theme.mjs lib-theme-graphite/theme.css
+```
+
+Passes the Crema v1 token contract (all Tier 1 tokens both modes, WCAG AA
+contrast floors, no font `@import`, no root `font-size`).
