Goal

Replace the CSS pixel-art frontend with a Canvas 2D rendered farm + HTML overlay for agent detail cards.

Assets Ready

assets/sprites/agent-{id}.png — 9 distinct 32x32 pixel art agent sprites:

cos: tall-thin, orange, clipboard
engineering: stocky, teal, hardhat, wrench
senior-eng: tall, purple wizard hat, crystal staff
trust: medium-wide, blue, helmet, shield
market: lean, green hood, magnifying glass
health: round, yellow, red bandana, red heart
content: medium, lavender beret, gold quill
presentations: tall, tophat, crimson cape
vault: small, mint, glasses, gold key

Also: agent-{id}-sheet.png — 4-frame walk cycle sprite sheets.

Technical Approach

Canvas 2D renders the farm map: grass background, dirt paths, building shapes, decorations
Sprite rendering: draw agent PNGs on canvas with smooth position interpolation
HTML overlay layer for: agent detail cards (click agent → card), status bar, connection indicator
Drop Three.js entirely — keep React + Zustand + WebSocketClient

Files to Create/Modify

src/frontend/App.jsx — Canvas-based farm container + HTML overlay
src/frontend/FarmCanvas.jsx — Canvas 2D rendering (buildings, paths, agent sprites)
src/frontend/AgentCard.jsx — HTML overlay card (click agent to inspect)
src/frontend/store.js — keep/update Zustand store
src/frontend/WebSocketClient.js — keep as-is
src/frontend/src/farm.css — update for overlay styles
src/frontend/index.html — update
src/frontend/package.json — remove three/fiber/drei deps

Design Requirements

Dark farm night background (#2D1B0E)
Buildings: Workshop, Studio, Cabins, Library, Shrine, Campfire
Dirt paths connecting zones
Pixel art trees, rocks, flowers as decoration
9 agents with smooth movement animation
Agent names visible on hover or permanently small below sprite
Click agent → card slides in from right with: name, department, status, current task
Bottom bar: connection status, agent count, clock/time

Build

Run cd src/frontend && npx vite build — must succeed.

✅ Complete

Replaced CSS pixel-art frontend with Canvas 2D farm + HTML overlay.

What was done:

FarmCanvas.jsx — Full Canvas 2D rendering: grass with texture, 5 buildings + campfire with animated flames, dirt paths, trees/rocks/flowers, building labels with dark pill background
Agent rendering — All 9 agent sprites loaded from PNGs (Vite public/ directory), lerp-based smooth movement, vertical bob for idle, sparkle particles for working, "..." bubble for thinking, red tint + "!" for blocked, grayscale+opacity for offline
AgentCard.jsx — Click-to-open HTML overlay card sliding from right with agent name, status badge, task, location zone, department
Cleanup — Removed OfficeScene.jsx, AgentSprite.jsx. Stripped CSS down to overlay/card/bar/connection styles. Title updated to "Spatial Office — Scobleclaw"

Build: ✅ passes (`npx vite build`)

Deployed: ✅ service restarted, serving from `src/frontend/dist/`

Commit: `9275854` — feat(frontend): Canvas 2D farm with real pixel art sprites and HTML overlay cards
