+  "task_description": "# Conceptual Explanations\n\nAdd brief 'Why This Works' explanations to each lesson that explain the concept behind the CSS property, not just the syntax. Include visual diagrams where helpful.\n\n## Rationale\nThe #1 criticism of Flexbox Froggy and similar tools is they teach syntax without explaining WHY. Codecademy and freeCodeCamp also criticized for 'just type this without understanding'. This is a major market gap we can fill.\n\n## User Stories\n- As a beginner, I want to understand WHY CSS properties work so that I can apply knowledge to new situations\n- As a self-taught developer, I want conceptual understanding so that I can build from scratch, not just follow tutorials\n\n## Acceptance Criteria\n- [ ] Each lesson includes a 'Concept' section explaining WHY the CSS property works\n- [ ] Explanations are concise (2-4 sentences) and beginner-friendly\n- [ ] Visual diagrams or illustrations included where helpful\n- [ ] Concept section is collapsible so advanced users can skip\n- [ ] Flexbox lessons explicitly explain container vs item distinction\n",
