The feed you were on is remembered per wallet; new ones start on Popular

2026-10-02T21:46:32Z

It was one device-wide key, so a new account opened on whatever the last one was reading (#gardenstr: the starter feed has the same id in every account). Now keyed by the wallet, re-read when a wallet opens (the feature outlives a sign-out), Popular when nothing is remembered, and the old device-wide key is dropped. A feed opened from a link stays put. Co-Authored-By: Claude Opus 5.5 Claude-Session: https://claude.ai/code/session_01Dmcrt9KyNDKVWFKnb8BREo

Pictures paint with the page: column-sized copies, and CORS that works

2026-10-02T17:09:28Z

Measured in the live tab (screencast frames): back from a profile, the feed's text was on screen ~200ms before its photo. The was loaded and complete on the first frame — a 3024px, 12-megapixel original that Chrome re-decodes whenever the page is rebuilt. - Post photos wider than the column at 2x are painted from an 1100px WebP copy made once (fetch, createImageBitmap, OffscreenCanvas) and kept in Cache Storage; it decodes in a few ms, decoding=sync, inside the same frame as the text. GIFs and small pictures keep the original; the lightbox opens the original. Profile banners use the same copies, warmed on prefetch. - corsFetch: primal's CDN caches its no-Origin answer without Vary: Origin, so a CORS fetch after the got that header-less copy and failed — which had written blossom.primal.net, m.primal.net and coinos.io off as 'no CORS', so their avatars never got local thumbnails and painted late from the originals. A refusal is now retried once past the cache before a host is blamed; the old list is dropped (nocors-v2). - DM list: the unread dot sits centred at the row's end, like the communities' below, instead of beside the time. - Balance card gear: the icon alone, no circle.

Tall videos fill the column with no side bars, up to the screen's height

A video in the feed paints at its own shape, not a 16:9 frame with black bands beside a portrait clip.

2026-10-01T01:36:29Z

The shape comes from the post's imeta dim when it gives one (Amethyst, Primal and others publish it), else from the clip's metadata fetched while the row warms (3 s cap), and is remembered on the device. The box is as wide as the column, never taller than 75vh; an unknown shape keeps 16:9. tools/feed-video-aspect-test.js: 3:4 and 16:9 clips measured ahead, a 9:16 one shaped by imeta alone (its file served too late to probe), a broken one.
