ScribblaZ UI Polish Archive

This page records the earlier tool-palette, most-recently-used color, and shape-tool polish work. It is superseded by the canonical ScribblaZ hub, architecture, game design, opcode reference, runbook, and verification checklist.

Historical changes captured here

• The shared ToolType and CanvasEvent contracts live in src/lib/gameState.ts; draw replay and rendering live in src/lib/canvasEngine.ts; canvas interaction is in src/components/DrawCanvas.svelte.
• Shape operations use the current TypeScript authoritative handler, server/match_handler.ts, which validates DRAW_SHAPE and relays accepted drawing operations (server/match_handler.ts:459-509). There is no current match_handler.lua authority.
• The controller’s MRU list keeps up to 8 unique colors: mruColors = [c, ...].slice(0, 8) in src/lib/ScribblaZController.svelte.ts:350-353, not four.
• PALETTE contains 15 curated entries in src/lib/gameState.ts:83-93. src/components/PaintColorPanel.svelte:32-64 renders those entries and adds a native <input type="color">; it is not a 16-color static palette.
• The completed dock/palette sprint is recorded in CHECKLIST.md:62-67: shortcut labels, the continuous 15-swatch strip plus native picker, aligned dock utilities, tighter HintBar chrome, and no runtime floating-ui/tooltip chrome.

This archive intentionally preserves the historical scope without treating it as the live source of truth for match flow or current UI verification.
