Shared links now unfurl with an image in WhatsApp, Telegram and anything
else that reads Open Graph, instead of showing the bare URL.
A dedicated og/ rendition is generated per photo: 1200px longest side,
quality laddered down until it fits under ~250 KB. WhatsApp drops the
preview entirely once the image passes ~300 KB, and the medium rendition
can exceed that, so it is not reused. Dimensions for og:image:width and
og:image:height are read back from the encoded file with DecodeConfig, so
they are emitted even when the rendition itself was skipped as up to date.
The og:image and og:url values are absolute via BaseURL; both crawlers
ignore relative image paths. Previews therefore only work against the
deployed base URL, not http://localhost.
Each timeline date heading now links to /day/<YYYY-MM-DD>/, a page
holding just that day's photos with a back link to the timeline.
renderDayPages writes one per groupByDay run; the ISO label doubles
as the URL slug.
The day-grouped timeline is now the site root (/, /page/N/); the flat
square grid moves to /grid/ (/grid/page/N/). Both are linked from the
profile header, separated by a divider.
Timeline pages pack whole day-groups until they reach the page size,
never splitting a day across a page boundary, so appended pages never
repeat a date heading — the infinite-scroll handler relies on this.
Page size is configurable via -page-size (default 60), threaded through
the Generator and exposed as services.photogallery.pageSize in the
NixOS module.
New /timeline/ page renders photos grouped into consecutive same-day
runs (ISO date heading plus per-day count), reusing the square grid.
groupByDay collapses the newest-first photo list; the page is not
paginated. Linked from the profile header.
Also corrects the serif font, which is Crimson Pro rather than Vollkorn,
and notes that .gitignore patterns here have to be anchored or they eat
the Kotlin package directory.
