Create or revise academic conference posters in HTML/CSS and export print-ready PDFs. Use for poster design, layout edits, and print export.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# posterly — HTML/CSS Academic Poster Workflow

A poster is **one HTML file** styled for an exact print canvas, rendered to PDF via Playwright + Chromium. Iterate by **measuring**, not eyeballing — the screen preview lies; only `emulate_media("print")` at the correct viewport tells the truth.

## Mental model

```
   HTML (with @page { size: W H })
     │
     ▼  print-emulate Chromium at W×96 × H×96 px viewport
     │
     ▼  data-measure-role tags identify columns/hero/footer-strip
     │
     ├──→ tools/poster_check.py measure  (HARD GATE — spread < 5 px,
     │                                    gap-to-strip ∈ [30,50] px,
     │                                    intercard gap ∈ [12,50] px,
     │                                    poster bbox aligns to page
     │                                    within ±2 px)
     ├──→ tools/poster_check.py preflight  (LaTeX residue, math `<`, missing imgs)
     ├──→ tools/render_preview.py  (PDF + thumbnail)
     └──→ tools/poster_check.py verify-final  (PDF page count / dims / size)

How to install

The exact contents, by fingerprint

mdr add chenruishuo/posterly/posterly@sha256:e3f8c2ce294410b2

The line at the top of this page pins the label git:20260919.d483f92, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
