// CMYK Conversion Guide - Added to provide customers with self-service CMYK conversion instructions
const CMYK_CONVERSION_GUIDE = `
================================================================================
🖨️ CMYK CONVERSION GUIDE (FOR PROFESSIONAL OFFSET PRINTING)
================================================================================
Your files are delivered in sRGB color profile, which is the universal standard for:
✓ Home/office inkjet printers
✓ Print-on-demand services (Printful, Printify, etc.)
✓ FedEx, Staples, and local print centers
✓ Most digital printing machines
CMYK is ONLY required for professional offset printing (magazines, large-scale commercial runs).

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚠️ IMPORTANT NOTES ABOUT CMYK CONVERSION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• CMYK has a SMALLER color range (gamut) than RGB. Some vibrant colors
(especially neon blues and greens) may appear slightly muted. This is physics.
• Most home printers work BETTER with sRGB files. CMYK is mainly needed
for offset printing and high-end commercial print shops.
• Always ASK your print shop which ICC profile they prefer BEFORE converting.
Common profiles: US Web Coated (SWOP) v2, Fogra39, Japan Color 2001
• Many print shops accept sRGB and do the conversion in-house with their
calibrated equipment for best results.
💡 PRO TIP: If printing at home or using print-on-demand, just use sRGB files.
Only convert to CMYK if your printer SPECIFICALLY requires it.

CONTEXT: Niche "${project.niche}", Type "${project.productType}".
CRITICAL INSTRUCTION - EXECUTION ORDER:
1. IDENTIFY the core subject in the ORIGINAL PROMPT (e.g., "A vintage glass jar of strawberry jam").
2. LOCK that subject. Do NOT change it. Do NOT remove it. Do NOT replace it (e.g., do not turn a jar into a teapot).
3. APPLY the User's stylistic changes (lighting, composition, color) *around* that locked subject.
OUTPUT STRUCTURE RULES:
- Start with the LOCKED SUBJECT description.
- Follow with the modified attributes based on the User's request.
- Final Output Format: "[LOCKED SUBJECT DESCRIPTION], [USER'S STYLISTIC REQUEST AS KEYWORDS]"
SAFETY PROTOCOL:
- If the request implies nudity, sanitize it to "artistic silhouette" or "covered".
- Output SAFE FOR WORK content only.

Generated by DigiCraft
FILE SPECIFICATIONS:
----------------------------------------------
1. [1_Print_Then_Cut_Ready.png]
- USE THIS FILE FOR DESIGN SPACE.
- Tech Specs: 300 DPI, RGB Color, Transparent PNG.
- Integrated Feature: 40px White Offset (Contour).
- Why: This file is pre-optimized for Cricut sensors. The white border ensures the machine cuts around the artwork, not into it.
2. [2_Cut_Mask_Silhouette.png]
- USE THIS IF AUTOMATIC TRACING FAILS.
- Tech Specs: 300 DPI, Pure Black (#000000), Transparent PNG.
- Purpose: If Design Space has trouble finding the edge of the artwork (e.g., light colors), upload this file as a "Cut" layer and place it directly behind the print file.
3. [3_Original_Design.png]
- RAW FILE.
- Purpose: Use this if you want to create your own custom offset size in Design Space or use for digital planning (GoodNotes/Notability).
CRICUT "PRINT THEN CUT" SIZE LIMITS (MAXIMUM):
----------------------------------------------
*Note: Dimensions include the sensor marks.*
[LETTER PAPER (8.5" x 11")]
- Max Cut Area: 9.94" x 7.44" (25.2 cm x 18.9 cm)
[A4 PAPER (21cm x 29.7cm)]
- Max Cut Area: 10.62" x 7.2" (26.9 cm x 18.3 cm)
[TABLOID / A3 (Large Format)]
- Tabloid (11" x 17"): Max 15.94" x 9.94"
- A3 (11.7" x 16.5"): Max 15.44" x 10.64"
IMPORTANT TIPS:
- Always check that your Upload Type is set to "Complex" in Design Space to preserve colors.
- Ensure your printer settings are set to "Photo Quality" and "Actual Size" (Scale 100%).
- Do NOT bleed the image; the white border is your safety zone.
