Font Rules

Font Family Standards

Language	Default	Alternatives
Chinese	Microsoft YaHei (微软雅黑)	,
English	Arial	Georgia, Calibri, Cambria, Trebuchet MS

fontFace: "Microsoft YaHei"  // Chinese text
fontFace: "Arial"            // English text (or approved alternative)

Use system-safe fonts for cross-platform compatibility. Header/body can use different fonts (e.g., Georgia + Calibri).

No Bold for Body Text

Plain body text and caption/legend text must NOT use bold.

• Body paragraphs, descriptions → normal weight
• Captions, legends, footnotes → normal weight
• Reserve bold for titles and headings only

// ✅ Correct
slide.addText("Main Title", { bold: true, fontSize: 36, fontFace: "Arial" });
slide.addText("Body text here.", { bold: false, fontSize: 14, fontFace: "Arial" });

// ❌ Wrong
slide.addText("Body text here.", { bold: true, fontSize: 14 });

Color Palette Rules (MANDATORY)

Strict Palette Adherence

Use ONLY the provided color palette. Do NOT create or modify colors.

• All colors must come from the user-provided palette
• Do NOT use colors outside the palette
• Do NOT modify palette colors (brightness, saturation, mixing)
• Only exception: Add transparency using the transparency property (0-100)

// ✅ Correct: Using palette colors
slide.addShape(pres.shapes.RECTANGLE, { fill: { color: theme.primary } });
slide.addText("Title", { color: theme.accent });
