lib-theme-phosphor: 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-phosphor
+
+**Terminal heritage, dark-first.** Phosphor's dark mode is its native identity: deep charcoal
+with a barely-there green undertone (never blue-gray, never pure black), cards stepping
+*lighter* off the background, and hairline light-alpha borders doing all the separation work —
+the elevation ladder exists but is whisper-quiet. One phosphor-green accent
+(`oklch(0.75 0.16 148)` carrying dark ink in dark mode; deepened to `oklch(0.45 0.12 150)`
+under white labels in light mode) is spent on the primary action, focus, and selection only.
+Light mode is the "paper terminal": warm-white paper, deep green-charcoal ink. Success is teal
+(hue 178) so state-green never collides with action-green. Dense/pro register, radius
+0.375rem, instant-feeling motion (100/180/280/400ms, springs aliased — no bounce),
+keyboard-first focus (2px offset phosphor outline on buttons, flush 1px ring on inputs),
+tabular numerals on tables and via the `.num` class.
+
+Built as one of four candidates for the calm-pro / dense-utility family (operator, console,
+and admin surfaces; Skyrise successor for developer-product screens).
+
+## Fonts
+
+The signature is **IBM Plex Mono for headings** (weight 500/600, slightly tight tracking) over
+**IBM Plex Sans** body, with Plex Mono again for code. Mono headings run wide, so the display
+ramp is deliberately modest.
+
+Per the Crema token contract, `theme.css` does **not** `@import` fonts. The consuming app must
+load them at the very top of its entry CSS (`app/app.css`):
+
+```css
+@import url("https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500;600&family=IBM+Plex+Sans:wght@400;500;600;700&display=swap");
+```
+
+Stacks (already wired in `theme.css`):
+
+- `--font-sans` / `--body-family`: `"IBM Plex Sans", -apple-system, BlinkMacSystemFont, "Segoe UI", sans-serif`
+- `--font-heading` / `--heading-family`: `"IBM Plex Mono", ui-monospace, "SF Mono", Menlo, Consolas, monospace`
+- `--font-mono`: same mono stack as headings
+
+## Validate
