The feed's post button is on screen the moment the feed is, while the page is still sliding in. "I'm still not seeing the Post button right away when I open the feed. It should be there from the start" (Adam, 2026-11-02): measured on his phone over DevTools, the button was in the page 87 ms after the Feed tap — 4109 px down, below an 809 px screen — and in place at 562 ms. It is position: fixed, and it was rendered inside the page, whose entrance animation puts a transform on it; a transform makes fixed descendants position within the page, so the button rode at the foot of the feed card until the slide ended. The feed now hands the button and the new-posts pill to the shell (a pageFloaters hook, taken once per render), which paints them beside the page, outside anything that animates; the pill's CSS no longer depends on sitting inside the page, and its phone-width rule stays after the base one so it still rides above the button. tools/feed-fab-anim-test.js taps Feed from the wallet and samples the button every frame of the slide: on screen from the first. The direct-mount harnesses (feed-new-posts, feed-streaming, feed-bottom-nav) paint the floaters as the shell doesHEADmaster
