Feat v0.6.14 visual polish

Fix v0.6.13 spacing regressions with half-step tokens (--sp-1h 6px,
--sp-2h 10px). Purge ~65 stale hex/rgba fallback values from var() calls
including all old gold #b38a4e references. Self-host DM Sans and JetBrains
Mono woff2 fonts, eliminating Google Fonts CDN dependency. Standardize
border-radius to three tokens (--radius-sm 4px, --radius 8px, --radius-lg
12px) across all kernel CSS and 12 extension packages.

Also fixes: theme settings showing resolved mode instead of stored preference,
surface-inner overflow causing notes scrollbar and chat input clipping at
high zoom, user menu drift at scale >100% from zoom-unaware fixed positioning,
and three undefined CSS variable references.

+## v0.6.14 — Visual Polish
+
+Systematic cleanup of stale values, self-hosted fonts, and rendering fixes.
+Final visual pass before the v0.6.15 usability survey gate.
+
+### Fixed
+
+- **v0.6.13 spacing regressions** — added half-step tokens (`--sp-1h` 6px,
+  `--sp-2h` 10px) and restored correct padding on `.sw-btn--sm`, `.sw-input`,
+  `.sw-menu__item`, `.sw-dropdown__option`, `.sw-tabs__tab`.
+- **Theme settings toggle** — showed resolved theme ("Dark") instead of stored
+  mode ("System"). Changed `appearance.js` to read `sw.theme.mode`.
+- **Notes surface scrollbar** — added `overflow: hidden` to `.surface-inner`
+  in `base.html`, preventing spurious scrollbar at any scale.
+- **Chat input clipped at high scale** — same `overflow: hidden` fix prevents
+  zoomed content from overflowing the surface container.
+- **User menu drift at scale > 100%** — `menu.js` now divides
+  `getBoundingClientRect()` coords by the CSS zoom factor, fixing position
+  for `position: fixed` menus inside a zoomed ancestor.
+- **Undefined variables** — `--text-secondary` (login), `--text-muted`
+  (user picker), `--text-1` (settings toggle) replaced with correct tokens.
+
+### Changed
+
+- **Stale fallback colors purged** — removed ~65 hex/rgba fallback values
+  from `var()` calls across 9 kernel CSS files and 3 extension packages.
+  Old gold theme color `#b38a4e` fully eliminated (9 instances).
+- **Self-hosted fonts** — bundled DM Sans and JetBrains Mono woff2 files
+  in `src/fonts/`. Replaced Google Fonts `@import` and login.html `<link>`
+  with local `@font-face` declarations. Zero external font dependencies.
+- **Consistent border-radius** — added `--radius-sm: 4px` token. Migrated
+  ~60 hardcoded `border-radius` values across all kernel CSS and 12 extension
+  packages to three tokens: `--radius-sm` (4px), `--radius` (8px),
+  `--radius-lg` (12px).
+
+### Updated
+
+- `docs/EXTENSION-CSS.md` — added `--sp-1h`, `--sp-2h` half-step tokens
+  and `--radius-sm` to the public CSS contract.
+
