+"""Credits tracking for Nous inference API responses.
+
+Parses x-nous-credits-* (and optional x-nous-tool-pool-*) headers from
+inference responses into a validated CreditsState dataclass.  Provides
+depletion detection (paid_access), subscription-cap used_fraction, and
+warn-once schema-version gating.  This is the hardened parser used by all
+live consumers (run_agent, tui_gateway) — not a dev-only shim.
+
+Header schema (x-nous-credits-* family):
+    x-nous-credits-version                    contract/schema version
+    x-nous-credits-remaining-micros           total remaining balance (micros)
+    x-nous-credits-remaining-usd              same, formatted USD string
+    x-nous-credits-subscription-micros        subscription balance (SIGNED; may be negative/debt)
+    x-nous-credits-subscription-usd           same, formatted USD string
+    x-nous-credits-subscription-limit-micros  subscription cap (PAIRED/optional)
+    x-nous-credits-subscription-limit-usd     same, formatted USD string (PAIRED/optional)
+    x-nous-credits-rollover-micros            rolled-over balance (micros)
+    x-nous-credits-purchased-micros           purchased balance (micros)
+    x-nous-credits-purchased-usd              same, formatted USD string
+    x-nous-credits-denominator-kind           "subscription_cap" | "none"
+    x-nous-credits-paid-access                "true" | "false" (STRING!)
+    x-nous-credits-disabled-reason            reason string (header omitted when null)
+    x-nous-credits-as-of-ms                   server-side timestamp (ms epoch)
+
+Tool-pool headers use a SEPARATE prefix:
+    x-nous-tool-pool-micros                   tool-pool balance (micros)
+    x-nous-tool-pool-gated-off                "true" | "false" (STRING!)
+
+Money is handled as micros ints only; *_usd values are preserved verbatim as
+the raw strings the server sent (never re-parsed to float).

+# Desktop Design System
+
+Conventions for the Electron desktop app (`apps/desktop`). Read this before
+adding a component, overlay, or style. The rule of thumb: **one source per
+concern, tokens over literals, flat over boxed.** If you reach for a raw color,
+a one-off shadow, a bespoke button, or a hardcoded `px-*` on a control — stop,
+there's already a primitive for it.
+
+## Principles
+
+1. **Flat, not boxed.** No card-in-card, no divider borders inside a panel.
+   Group with whitespace and a single hairline, never nested rounded boxes.
+2. **Borderless + shadow for elevation.** Overlays float on `shadow-nous` + a
+   `--stroke-nous` hairline, not hard borders.
+3. **One primitive per concern.** One `Button`, one set of control variants,
+   one `SearchField`, one `Loader`, one `ErrorState`. Migrate onto them; don't
+   fork.
+4. **Tokens, not literals.** Reference CSS vars (`--ui-*`, `--shadow-nous`,
+   `--theme-*`), never raw hex / ad-hoc rgba in components.
+5. **Style lives in the primitive.** Variants and sizes own padding, radius,
+   color, chrome. Call sites pass a `variant`/`size`, not `className` overrides
+   that re-specify those.
+
+## Surfaces & elevation
+
+Every overlay / dialog / toast (boot-failure, install, notifications,
+model-picker, onboarding, prompt-overlays, updates, base `Dialog`) uses:
+
+```
+shadow-nous           /* downward-weighted, layered contact→ambient falloff */
+border-(--stroke-nous) /* currentColor hairline, theme-adaptive */
+```
+
+Both are CSS vars in `src/styles.css` — tune in one place, everything inherits.
+Don't add per-overlay `shadow-[…]` or `border-(--ui-stroke-secondary)`
+one-offs; if elevation needs to change, change the token.
+
+## Stroke & color tokens
+
+| Token | Use |
+| --- | --- |
+| `--ui-stroke-primary…quaternary` | hairlines, in descending strength |
+| `--ui-stroke-tertiary` | the default in-panel divider / list hairline |
+| `--stroke-nous` | the overlay hairline (pairs with `shadow-nous`) |
+| `--ui-text-primary / -secondary / -tertiary` | text hierarchy |
+| `--ui-bg-quaternary` | soft control fill (secondary button) |
+| `--chrome-action-hover` | hover fill for quiet controls |
+| `--theme-primary`, `--ui-accent` | brand/accent |
+
+Never hardcode `border-gray-*`, `bg-white`, `text-black`, etc. The white tile in
+`BrandMark` is the one sanctioned literal (the mark needs a fixed backdrop).
+
+## Buttons — one component
+
+`src/components/ui/button.tsx` is the single source. Pick a `variant` + `size`;
+do **not** pass `h-*`, `px-*`, `py-*`, or icon-size overrides.
+
+**Variants:** `default` (primary), `destructive`, `secondary` (soft fill —
+the default non-primary look), `outline` (transparent + 1px inset ring, no
+fill/shadow), `ghost`, `link`, `text` (boxless quiet inline — "Cancel",
+"Clear"), `textStrong` (bold underlined inline affordance — "Change",
+"Open logs").
+
+**Sizes:** `default`, `xs`, `sm`, `lg`, `inline` (flush, zero box — for buttons
+that sit inside a heading/sentence; replaces `h-auto px-0 py-0`), and the icon
+family `icon` / `icon-xs` / `icon-sm` / `icon-lg` / `icon-titlebar`.
+
+Notes:
+- Text buttons are square (no radius) and sized by padding + line-height (no
+  fixed heights). Only icon buttons carry the shared 4px radius.
+- SVGs inherit `size-3.5` (`size-3` at `xs`). Don't re-set icon size.
+- Polymorph with `asChild` when the button must render as a link/Slot.

+
+- **`controlVariants`** (`src/components/ui/control.ts`) is the shared shape for
+  `Input` / `Textarea` / `SelectTrigger`. New text-entry controls compose it.
+- **`SearchField`** — borderless, underline-on-focus, auto-width. The only
+  search input. Don't build boxed search bars; don't wrap it in a bordered tile.
+  Empty lists hide their search field.
+- **`SegmentedControl`** — the choice control for small mutually-exclusive sets
+  (color mode, tool-call display, usage period). Replaces radio piles and
+  pill rows.
+- **`Switch`** (`size="xs"`) — bare, with `aria-label`. No bordered text wrapper.
+
+## Layout
+
+- **Gutters:** `PAGE_INSET_X` (`src/app/layout-constants.ts`) for page side
+  padding; `PAGE_INSET_NEG_X` to bleed a child to the edge. Don't hardcode
+  `px-6`/`px-8` on pages.
+- **Master/detail overlays:** `OverlaySplitLayout` + `OverlaySidebar` /
+  `OverlayMain`. Cron, profiles, etc. ride this — don't rebuild a titlebar
+  shell.
+- **Rows:** `ListRow` (settings `primitives.tsx`) for label/description/action
+  rows. Flat, flush-left; no per-row indentation that fights flush headers.
+- **No dividers between rows** unless the list genuinely needs them; prefer
+  spacing. When you do need one, it's a single `--ui-stroke-tertiary` hairline.
+
+## Feedback & empty/error/loading states
+
+- **Loading:** `Loader` (`src/components/ui/loader.tsx`) — animated math/ascii
+  curves (`lemniscate-bloom` for long ops). Never ship the literal text
+  "Loading…".
+- **Errors:** `ErrorState` + the canonical `ErrorIcon` (no bg chip). One look
+  for the React boundary, in-dialog errors, and the boot-failure banner. Pass
+  nodes for title/description so Radix `DialogTitle`/`Description` can flow
+  through for a11y.
+- **Logs:** `LogView` — no bg, hairline border, tight padding, small mono.
+  Every place we surface raw logs uses it.
+- **Empty:** `EmptyState` / `EmptyPanel` — don't hand-roll centered empties.
+
+## Iconography & brand
+
+- **`Codicon`** is the icon set. No mixing icon libraries inline.
+- **`BrandMark`** (`src/components/brand-mark.tsx`) is the brand glyph — the
+  `nous-girl` mark on a white tile, softly rounded, identical in light/dark.
+  It replaced scattered Sparkles glyphs in updates / onboarding / about. Use it
+  for hero/brand moments; don't reintroduce decorative star/sparkle icons.
+
+## Motion
+
+- Quick, functional transitions (~100ms on controls). Respect
+  `prefers-reduced-motion` for anything beyond a fade.
+- Choreographed exits (e.g. onboarding's "matrix" fade-down) stagger per-element
+  then settle the surface — the outer container's fade is *delayed* so it
+  doesn't swallow the inner animation. Don't let a global fade race the detail.
+
+## i18n
+
+- Every user-facing string goes through `useI18n()` (`src/i18n/context.tsx`).
+  No literals in JSX.
+- **Update all locales together** — `en`, `ja`, `zh`, `zh-hant`. A string change
+  in `en.ts` that skips the others is a regression (drifted punctuation,
+  stale labels). Keep trailing-punctuation and tone consistent across all four.
+
+## State (TypeScript)
+
+Mirrors the repo TS style (see root `AGENTS.md`):
+
+- Shared/cross-component state → small **nanostores**, not prop-drilling.
+  Each feature owns its atoms; shared atoms live in `src/store`.
+- Rendering components subscribe with `useStore`; non-render actions read with
+  `$atom.get()`.
+- Colocated action modules over god hooks. A hook owns one narrow job.
+- Keep persistence beside the atom that owns it. Route roots stay thin.
+- Prefer `interface` for public props; extend React primitives
+  (`React.ComponentProps<'button'>`, `Omit<…>`).
+
+## Affordances
+
+- `cursor-pointer` at the primitive level (Button, dropdown/select) — don't
+  hardcode it per call site.
+- Global focus-ring reset; titlebar actions have no active-background state.
+- `Esc` closes every dismissable overlay/dialog (install/onboarding excluded);
+  close is an x-icon, not the word "Close".
+
+## Before you add something — checklist
+
+- [ ] Reuse a primitive (`Button`, `SearchField`, `SegmentedControl`,
+      `ListRow`, `Loader`, `ErrorState`, `LogView`) instead of forking one?
+- [ ] Tokens (`--ui-*`, `shadow-nous`, `--stroke-nous`) — zero raw colors /
+      one-off shadows?
+- [ ] No `className` overriding a primitive's padding / size / radius / chrome?
+- [ ] Overlay uses `shadow-nous` + `border-(--stroke-nous)`, no hard border?
+- [ ] Flat — no card-in-card, no gratuitous row dividers?
+- [ ] All four locales updated for any new/changed string?
+- [ ] `cursor-pointer`, focus ring, and `Esc`-to-close behave?

 ### Install with Hermes (recommended)
 
-Add `--include-desktop` to the [one-line installer](../../README.md#quick-install) and it sets up the agent and builds the desktop app in one go:
-
-```bash
-curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash -s -- --include-desktop
-```
-
 Already have the Hermes CLI? Just run:

+ * Wait-loop: bounded (matches POSIX's ~30s cap) so a never-exiting / mismatched
