Extracts the visual theme (colors, typography, radius, spacing, shadows) of a public website provided by the user and produces a shadcn/ui + Tailwind CSS v4 compatible token block, ready to paste into the project's `globals.css` (or `app.css`) inside `@theme` and `.dark`. Uses the chrome-devtools MCP server to drive a real Chromium instance (no Playwright). Use when the user asks to "extract the theme of <url>", "reverse-engineer the design tokens of <site>", "copy the look of <site> into shadcn", "build a tailwind v4 theme from <url>", or mentions extract-theme / theme extraction / design tokens from a URL.

coop-session

Architecture blueprint for drop-in/drop-out co-op (2-4 players) in open-world action RPGs, modeled on Genshin Impact's lobby system, plus the wider netcode and co-op-design landscape: the session lifecycle (unlock gates, world-level join rules, join/leave/kick flows, the host's-world-as-server-instance model, late-join state snapshots), the authority spectrum (server-hard economy, client-trusted ephemera — the datamined Genshin hybrid), replication at architecture level (prediction, reconciliation, interpolation, relevance), the co-op content rules matrix (host-only / instanced / shared as data — structural anti-grief), enemy scaling, topology trade-offs (dedicated instances vs listen-server vs P2P); the netcode-model landscape (deterministic lockstep for RTS, rollback for fighting games, client-server lag compensation / favor-the- shooter for FPS, MMO-scale interest management / sharding / single-shard time dilation / server meshing, matchmaking and SBMM — Elo/Glicko/ TrueSkill, relay vs dedicated, NAT trave

inventory-equipment
