M7: download a missing free font from the Missing fonts window (#754) (#1510)

A missing family the suite's font store has (Google Fonts, Noto) gets a
Download button. The first one asks the user to allow downloading fonts,
then craft-libs' craft-font-store installs pinned, checksum-verified files
into the Craft apps' shared font folder on a thread of its own. The font
scan reads that folder; once installed the text fits the real font.

font.download / font.downloads drive the store as its agent: refused while
downloading is off, never able to turn it on. Desktop only.

 | Date | Change | Summary |
 |---|---|---|
+| 2026-10-29 | minor | #754, #1025: the Missing fonts window offers Download for a family the suite's font store has (Google Fonts, Noto: craft-libs' `craft-font-store`, its pinned indexes compiled in). The first Download asks the user to allow downloading fonts (off until then; the setting is the Craft apps' shared one); the files download on a thread of their own, each checked against the index's size and sha256 before it is installed into the shared font folder, which the font scan now reads; the row shows progress or why it failed, and once installed the file's text fits the real font and the family leaves the list. `font.download {family}` and `font.downloads` are commands, but no command turns downloading on; agents install only while the user has it on. Desktop only. No cancel, no turning it off from FigCraft, no substitute picker. Tests: `fonts::download::tests`, `missing_fonts_tests`. Numbers unchanged |
 | 2026-10-29 | minor | Web wasm size (#1472): the release wasm is 23,915,213 bytes (22.8 MiB), down from 25,982,540 (24.8 MiB), 1.2 MiB under the gate. Catalog rows hold their plural forms behind a reference (two words, not eight) and the browser build compiles with wasm SIMD, so the glyph rasterizer's scalar fallback is left out; the 24 MiB gate in `packaging/web/package.sh` is restored. The browser now needs WebAssembly SIMD (Safari 16.4 or later). Numbers unchanged. |
 | 2026-10-29 | minor | Shadows of images with transparent pixels (M3, #1289): a drop shadow is cast from the picture's alpha and hidden only behind its pixels, not its whole box (a transparent PNG's shadow was cut away inside its bounding box), unless shown behind transparent areas; its inner shadow shades the inside of its alpha, not the box's edge; the same for Fit images, crops smaller than the box and pattern fills. Opaque pictures that fill their box keep their outline (spread still offsets it exactly); each image is scanned for transparency once. Canvas, PNG, SVG (knocked out by the layer's alpha; an inner shadow embeds a render) and PDF (`image_shadow_tests` in render and svg). Numbers unchanged |
 | 2026-10-29 | minor | M1, #1464: Crop image. Object ▸ Crop image, the right-click menu (one image layer) and a crop button on the image fill row run `image.crop`: the layer's top visible image fill (or the one `index` names) switches to Crop with the picture left where Fill or Fit drew it, as one undo step, and the canvas enters crop mode (the image shows dimmed outside the layer, whose box gets corner brackets and edge bars; the layer's edges and corners crop it with the picture held still, the image drags to move and its corners scale it; Enter, Escape or a click outside finishes). A layer without an image fill, or several layers, are refused with a reason. Tests: `image_crop_tests`, `crop_image_tests`. Numbers unchanged (the menu item is FigCraft's own and not counted by `parity`) |
