+// Chinese font data (VLW format) for OLEDDisplay-based TFT rendering via LovyanGFX.
+//
+// HOW TO GENERATE FONT DATA:
+//
+// Option 1: Adafruit GFX fontconvert (simpler, fewer glyphs)
+//   brew install adafruitnrf52-gfx-fontconvert  # macOS
+//   fontconvert NotoSansSC-Regular.ttf 16 > zh_cn_16.h
+//   The output is a GFXfont struct. LovyanGFX can use this via ft_gfx type.
+//
+// Option 2: LovyanGFX VLW format (recommended, more features)
+//   Use the LovyanGFX font converter script to generate a .vlw file from TTF
+//   Then embed the .vlw binary as a byte array using xxd:
+//   xxd -i zh_font_16.vlw > zh_font_16_data.h
+//
+// Option 3: Use BDF fonts (free, text-based)
+//   WenQuanYi bitmap fonts: http://wenq.org/
+//   Convert BDF to VLW using LovyanGFX tools
+//
+// FONT SIZE GUIDELINES:
+//   - 16px: Minimum readable Chinese on 320x240 TFT (~20 chars per line)
+//   - 20px: Better readability, ~16 chars per line
+//   - 24px: Title/header text, ~13 chars per line
+//
+// CHARACTER SET RECOMMENDATIONS:
+//   - GB2312 Level 1: 3755 commonly used simplified Chinese characters
+//   - Plus ASCII 0x20-0x7E for punctuation and Latin characters
+//
+// PLACEHOLDER DATA - Replace with generated font binary:
+
+#include "OLEDDisplayFontsZH.h"
+
+// Placeholder font data.
+// Replace with actual generated VLW/Gfx font binary from a Chinese TTF file.
+// The array below is intentionally minimal - it won't render any characters
