Matches the Phase 1 design_system pattern the brief points at: own lint config,
own tests, own coverage gate enforced in CI.
The lint script was declared but unrunnable -- there was no eslint flat config,
and the build tsconfig excludes tests (correctly; they must not ship in dist/),
so type-aware linting had no project for them. Adds eslint.config.js and a
lint-only tsconfig that widens the include without emitting. Running it surfaced
one real defect: nth() interpolated a number into a template literal without
String(), which the consumers' configs would have flagged.
The gate also checks that the committed dist/ matches a fresh build. This is not
theoretical -- the check caught the stale dist/ produced by that very String()
fix on its first run. A stale dist/ in a tag ships old code to every consumer
with no error anywhere, which is the one failure mode this packaging choice
introduces. dist/ is excluded from the whitespace hooks: they would "fix"
generated output that the next build immediately reverts.
CI additionally re-runs the categorical ramp's constraint proof, so the palette
cannot regress silently either.

The web counterpart to design_system (Dart): one :root block of frozen tokens
plus the components that were duplicated across repos. Extracted from
dufs-cloud and awesome-mcp-explorer, which both now consume it.
- tokens.css: the frozen palette, spacing/radius/type scales, shadow policy and
focus ring, under the canonical variable names from unified-design-system.
Also ships the global :focus-visible rule, rather than leaving each consumer
to remember it.
- RangeSlider: reconciled from the two drifted copies. Takes the accessible DOM
from awesome-mcp-explorer (real <button> thumbs with role="slider" and the
aria-value* trio) and grab-the-nearer-thumb from dufs-cloud. Keyboard support
(arrows/PageUp/PageDown/Home/End) is new: both donors were pointer-only, which
the design system rules out, and an arrow-key-deaf role="slider" is an ARIA
role that lies.
- quantile.ts + fuzzyMatch: the genuinely duplicated helpers.
FilterBar is deliberately absent. The two same-named components share no
structure -- a horizontal <select> strip over files vs a vertical tri-state chip
sidebar over servers, with disjoint FilterState, props and sort keys. It is the
name-collision-is-not-a-duplicate trap, so extracting it would ship a widget
nobody imports.
dist/ is committed (and un-ignored against the root rule) because Vite does not
transpile dependencies; consumers stay at zero config. Consumed via pnpm's
&path:/web_ui suffix -- npm cannot install from a subdirectory of a git repo.
