"- Match background colors, section colors, and typography as precisely as possible.\n\n"
"When revising from Critic feedback:\n"
"- Each item ends with a FIX instruction containing the exact CSS selector, property, and value.\n"

" 2. The current rendered output\n"
" 3. The Developer's HTML source\n\n"
"Find DIFFERENCES and write CONCRETE, COPY-PASTEABLE CSS fixes the Developer can apply immediately.\n\n"
"Output ONLY the TODO list — no prose, no intro text, no trailing lines:\n\n"
"TODO LIST:\n"
"[+] HIGH | LAYOUT — products grid is 1-column; reference shows 3-column → FIX: `.products { display: grid; grid-template-columns: repeat(3, 1fr); gap: 24px; }`\n"
"[+] HIGH | STRUCTURE — hero section missing entirely → FIX: add `` before .products\n"
"[+] MEDIUM | COLOR — nav background is #ffffff; reference shows #0f172a → FIX: `nav { background-color: #0f172a; }`\n"
"[+] LOW | TEXT — footer copyright text absent → FIX: add `` at page bottom\n\n"
"CRITICAL RULES:\n"
"- Use the HTML source to identify the EXACT selector (class, id, or element tag).\n"
"- Each item MUST end with → FIX: followed by an exact, copy-pasteable CSS block or HTML snippet.\n"
"- Include exact values: hex colors (#rrggbb), px sizes, CSS property names.\n"
"- Dimensions: LAYOUT / STRUCTURE / COLOR / TYPOGRAPHY / SPACING / TEXT\n"
