Reference popups (provider-rendered: arXiv, Wikipedia, CrossRef, …)
get a glanceable layout: wider container (560px), larger title and
body type, and a full-width image banner under the source label.
Internal page previews and item-card popups (new/library pages) keep
the compact layout — the shared popup element toggles
.link-popup--rich per show based on the rendered content.
- arXiv: a new best-effort enrich step fetches the paper's LaTeXML
HTML rendition and pulls the first figure as a lead image. Enrich is
time-boxed (1.8s) so the metadata popup is never held hostage; late
results refresh the cache for the next hover. Figures letterbox with
object-fit: contain (plots must not crop); Wikipedia photos
cover-crop with an upper focal point. width/height attrs reserve
aspect ratio so positioning is stable before the image loads.
- Wikipedia thumbnails request 480px for the banner width.
- nginx: new ^~ /proxy/arxiv-html/ location backed by arxiv.org proper
(export.arxiv.org serves the Atom API but 429s the /html/ asset
tree); 404s cached 1d (the common no-HTML-rendition case). All four
proxy locations switched to ^~ — without it, static-assets.conf's
per-extension regex location outranks plain prefixes and serves a
local 404 for any proxied URL ending in an image extension, which is
exactly how the first figure fetch failed.
Installed and verified live: proxied page (200, 298KB), figure (200
image/png), API unchanged, no-rendition 404 path; the full client
resolution chain (relative src -> proxy path -> guard -> image)
validated against production.
