Fini d939b1c88f fix(canvas,ai): path icon rendering, text centering, and stream reliability ... - Path icons: use uniform scaling (preserve aspect ratio instead of squishing), fillRule 'evenodd' for compound paths with cutouts, transparent fill for stroke-only icons, strokeUniform to keep stroke width constant - Text centering: use actual Fabric rendered height (fontSize * lineHeight) for cross-axis centering instead of declared height - Hover cursor: use default arrow instead of move/crosshair on elements - Stream reliability: server sends keep-alive pings every 15s during API TTFT, forwards thinking_delta events, client resets timeout on ping/thinking chunks - Remove silent fallback from streamChat to generateCompletion (was causing double requests when server is unresponsive) - Add 3-minute timeout to generateCompletion - AI prompts: instruct model to preserve icon aspect ratios		2026-02-20 03:04:13 +08:00
