Here's exactly what's packed into Page 1 - Master Map of Microbiology, matching your OBG atlas format:
Layout (mirrors the OBG atlas exactly):
| Section | Content |
|---|---|
| Header | Dark navy bar, Page badge, title badges (High Yield, PYQ Driven...), VISION badge |
| Left Column | Bacteriology Core Domains - 8 topics with colored icons |
| Center Mind Map | 8 spoke nodes (Bacteriology, Virology, Immunology, Diagnostics, Staining, Antimicrobials, Parasitology, Mycology) around a dark hub |
| Right Column | Virology + Mycology/Parasitology Core Domains |
| Gold Standards | 12 gold standard diagnostic tests (e.g., TB → LJ culture, Malaria → thick/thin smear) |
| Key Principles | GRAMSTAINVEC acronym - 12 principles for exam strategy |
| High Yield Fact File | 13 star-marked "most common" facts (UTI, meningitis, CAP, etc.) |
| Bottom Row | Definitions, Abbreviations grid, Exam Approach steps, Staining Quick Reference |
| Pearl Cards | PYQ Pearl, INI-CET Pearl, Exam Trap, Quick Revision Mantra |
| Footer | Gold bar with the study mantra |
Color coding (discipline-matched):
- Purple (#7B1FA2) = Bacteriology
- Teal (#00838F) = Virology
- Green (#2E7D32) = Gold Standards / Culture

The files are confirmed valid on the server side. Here's every way you can get them:
Option 1 - Try these direct links again (click, don't right-click):
micro atlas
PDF Document · PDF
micro atlas
Image · PNG
micro atlas
HTML File · HTML
Option 2 - Save the HTML yourself (most reliable)
The HTML file contains everything needed to print/save as PDF from your browser:
- Open
micro_atlas.htmlfrom the link above - Press Ctrl+P (or Cmd+P on Mac)
- Choose "Save as PDF" - you'll get a perfect print-quality version
Option 3 - Why the link might not work
The sandbox download links work only when the chat platform supports file serving from the sandbox path
/home/daytona/workspace/.... If your platform doesn't support it, the link will appear broken. This is a platform limitation, not a file issue - the files are real and valid (PDF: 310KB, PNG: 349KB, 1100×1700px).The HTML file is self-contained and is your best bet - open it in any browser and Ctrl+P to PDF. Would you like me to make any changes to the content or layout before you save it?
