Image ratios

Modern CSS `aspect-ratio` everywhere. Per-surface ratios are locked — they encode the editorial use case (cover image, portrait, country thumb, file cover).

Locked ratios per surface

16:9 · Event hero / Event card thumbnail

Calendar event hero image + every event-card variant’s media slot.

16:9 · Coverage hero / Coverage card

Editorial coverage anchors visually to the parent event — same ratio.

16:9 · Editorial article / Startup card logo canvas

Standard editorial cover ratio. Logo canvas uses 16:9 with the logo centered inside.

4:3 · Country card thumb / Related event thumb

Smaller secondary thumbnails when the card carries dense text content.

3:4 · Founder File cover (portrait)

Files are book-like — portrait covers across listing, featured, details, and reader surfaces. SVG editorial fallback when no upload.

1:1 · Founder portrait

Square portrait inside Founder Cards. Forces consistent rendering across listing densities.
