   专业工具 / 高科技感 · 浅色主题 design system for the /ai-tools section
   Shared across: ai_tools, ai_typo_work, ai_typo_tool, ai_polish_tool,

   Concept: a sheet of proofing paper on a drafting / copy-editing desk.
   - drafting-grid backdrop, white "proof sheet" panels
   - registration / crop marks on hero corners (the signature element)
   - ruler ticks, hairline rules, mono "instrument readout" data type
   - accents = real proofing-tool inks:
       emerald section stays for legacy, but each tool owns a real ink:
       错别字 = 朱红校对笔 (red proof pen)
       润色   = 蓝铅笔 (editor's blue pencil)
