Weather was the richest example that already spanned more than one target -- live forecasts, city management, scrollable rails -- but it ran only on the board, the web simulator and Android. It is also the one app whose layout makes a good cross-platform reference, so the gaps were worth closing. Its stylesheets are authored for the 410x502 board at ratio 1.5, which is 273 logical px wide, so it declares that as its design width and every phone and desktop target scales it from there. Two rules earn their place behind a tall viewport: the forecast's 68px cap keeps it from crowding the hero on the board but leaves a dead band on a phone, and the backdrops were rendered at panel size, so they need to stretch rather than letterbox. The board's logical height is 335, so neither rule ever reaches it. The `fit` attribute on the backdrop images had to go: it is recorded as an inline style, and inline styles replay after class rules, so it would have overridden the media-scoped object-fit without a trace. The CSS already says contain, so the board sees no change. Display.setBrightness and setFlushConfig stay. They are ESP32 tuning and inert setters elsewhere; only the comment needed to say so.

Two rules were added to make weather look acceptable on the phone and desktop targets, and both were the wrong shape: they bent the app to fit the renderers instead of leaving the CSS correct. `object-fit: fill` was chosen for the backdrops purely because it is the one value all three backends happen to agree on -- macOS maps `cover` to a proportional fit and the Android view stretches whatever it is given. The forecast rule was worse than cosmetic. `max-height: none` is not a length the engine understands: it reaches parseLengthForNode, strtod stops at the `n`, and the property lands as 0 -- which clampSize treats as a hard maximum because 0 is not the kUnset sentinel. With `min-height: 0` there is no floor to restore it, so `.forecast` computed to height 0 and iOS, which hides a view of zero size along with its whole subtree, dropped the section head and both rails. The board never saw it because the rule sits behind a tall-viewport query its 335 logical px never match. The dead band under the rails on a tall screen is what the reference rendering shows too, so it stays until the design says otherwise in CSS.

designWidth is 273, so a 410px window gave a device pixel ratio of 1.502 and every CSS length was rounded to an integer on its own. A 1px padding became 2px on each side, so a 26px cell had 35px of content where CSS gives it 36 -- enough to wrap "10 PM" onto a second line and make the row overflow. 546 is 2 x 273, so every length in the stylesheet lands on a whole device pixel and the rounding divergence disappears on this target.

The key was month*744 + day*24 + hour, so on 31 December the hourly entries for January sorted below the current hour: the scan in applyApiWeather walked past the end of the array and every hourly slot came out blank. Scaling the year needs a multiplier above the 9695 intra-year maximum (12*744 + 31*24 + 23), which 8928 is not, so the key is nested rather than flat. Checked monotonic across 14,784 sampled points from 2020 to 2030. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
No @geastack/windows dependency: weather runs the `gea` runtime, and notes-jsx already targets Windows the same way without declaring it. Only the windows-native runtime needs that package. Built and run against the Win32 target: the backdrop, the translucent chip surfaces and the forecast rail below the metric strip all render, and localStorage survives a restart. The `.screen` padding is not applied (--safe-x: 17px, content still sits at x=0), which is a pre-existing renderer gap, not a target-enablement one.

The backdrop art is the 410x502 panel itself; object-fit: cover fills a taller desktop window instead of leaving bands above and below it. City chips drop the extra bottom padding so their labels sit centred. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Add Windows to the Weather target list.
The manifest enables windows, but the catalog row omits it. Add windows so the row lists all enabled targets. geaos is correctly excluded because the manifest disables it.
