价签版式原 100% 硬编码在四条渲染路径。引入 label_template.dart 声明式模型(纸张/打印/抬头/文字栈/QR/条码),builtinDefault() 逐值冻结 重构前常量;画布渲染器 _renderLabelBitmap 与热敏 _printFlatLabelThermal 改为纯读模型,坐标统一到画布权威。facade/web stub 加 template 可选参 (null→默认,现有调用点行为不变)。 新增 label_render_golden 零回归基准:默认模板渲染与重构前逐像素零 diff。 附评审通过的设计文档 label-template-editor.html(5 项决策)。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Bupi8Kdqkfx2N5acFsHTx5
