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.

The root cause of 'PDF/arXiv previews simply do not work' was twofold:
1. nginx/popup-proxy.conf was never installed on the VPS — every
/proxy/* request (arXiv, PubMed, Internet Archive) returned nginx's
default 404. Now installed (snippets + http{}-context cache/limit
zones in conf.d, included in the vhost, nginx -t verified, reloaded).
2. The snippet itself had a latent bug that only surfaced once
installed: with a VARIABLE upstream, a URI part on proxy_pass is
passed literally — every request hit the upstream's homepage
(archive.org HTML where JSON was expected, arXiv 429s, NCBI doc-page
redirects). Fixed with explicit prefix-strip rewrites; bad cached
responses purged. All three proxies verified returning real data,
including a live arXiv title resolve.
Client-side improvements:
- arXiv match covers old-style IDs (cs/9901002, math.GT/0309136,
cond-mat/...v1) alongside new-style, and .pdf-suffixed /pdf/ URLs
(regex verified against six forms)
- Wikipedia popups show the article's lead image: pageimages rides
along the existing extracts call (pithumbsize=320), rendered via a
new https-only image slot in renderPopup with float styling;
upload.wikimedia.org added to the CSP's img-src
- pdf-thumbs now walks all of static/ (pdfjs pruned), so /cv.pdf and
/resume.pdf — the most-linked internal PDFs, previously thumbnail-less
and therefore popup-less — get hover previews

- gallery.js: math/score focus overlays are keyboard-activatable
(role=button, tabindex, Enter/Space) and focus return on close lands
on a focusable trigger (AUDIT §5.7)
- annotations.js: marks are focusable; Enter/Space pins the tooltip
with focus moved to its Delete button, Escape dismisses — the delete
affordance is finally reachable without a mouse (§5.7)
- transclude.js: nested transclusions resolve (depth-capped at 3, with
ancestor-chain cycle rejection rendering the existing error style);
collapse.js reinit is idempotent via data-collapse-bound (§5.7)
- copy.js excludes the button label from code-less <pre> copies;
score-reader.js stops rewriting plain loads to ?p=1; search-filters
treats non-numeric threshold input as inactive instead of a
match-everything >=0 filter; selection-popup no longer re-summons
the toolbar while typing capitals in the annotation picker (§5.8)

- semantic-search.js: generation token prevents stale results from
rendering over newer queries; in-flight dedup on the index fetch;
index/meta size consistency check fails loudly instead of NaN
ranking (AUDIT §5.5)
- lightbox.js: triggers keyboard-activatable (role=button, tabindex,
Enter/Space); Tab trapped inside the aria-modal overlay, modeled on
gallery.js (§5.6)
- nav.js: portal toggle persists via guarded safeStorage so
storage-blocked contexts can't kill the toggle (§5.7)
- popups.js: provider url() throws (malformed percent-encoding) are
treated as no-popup; future dates render nothing instead of
"N days ago" (§5.7)
- search.js: missing PagefindUI degrades to a console warning instead
of aborting the whole handler (§5.7)
- citations.js: deleted — dead code superseded by popups.js (§5.7)

- score-reader template: load utils.js before theme.js — without
lnUtils.safeStorage the saved theme/text-size never restored on
score pages (AUDIT §5.1)
- search-filters: expand trailing-slash pathnames to .../index.html
before the epistemicMeta lookup; clean-URL pages were silently
bypassing every active filter (AUDIT §5.2)
- viz: treat cappuccino as a dark theme so charts stop rendering
near-black marks on a dark brown background (AUDIT §5.3)
- collapse: namespace section-collapsed keys by pathname (Pandoc
auto-slugs recur across essays) and go through safeStorage like the
rest of the site (AUDIT §5.4)

build/Now.hs renders the .now-stamp-relative phrase ("3 days ago") at
build time against the build machine's clock; a page served days later
from cache or a CDN would then read stale. now.js recomputes the
phrase in the browser from the <time datetime> attribute (an
unambiguous YYYY-MM-DD) against the visitor's clock, with bucket
thresholds that mirror Now.hs:relativeTime exactly so the no-JS
fallback and the recomputed value agree.
* static/js/now.js — the recomputation script.
* templates/default.html includes it via $if(now)$ so it only loads
on the Current page.

Internal-page hover popups now show the source's monogram alongside
the title / abstract / metadata when one exists. Two-column grid is
gated on .has-monogram so popups for pieces without an authored mark
keep their default single-column body. The serialised SVG comes from
the rendered page's own .frontmatter-mark--monogram figure, excluded
when it is the symmetric-layout placeholder roundel so empty-slot
pieces do not get a fake mark in the preview.
