A smaller web template

A web export ships a template built without the editor: 18.9 MB raw and 5.1 MB brotli, where the editor's module is 25.4 MB and 7.0 MB.

• A web export ships compiled scripts, as every other target does, and the template has no Rune compiler: 1.0 MB of code.
• Every shader the game draws with is linked at export and deflated into the pack, 9 KB for a game with no materials of its own, so the template has no WESL linker: 1.4 MB.
• The exporter, the project store and a tab's editor entry points stay behind the editor feature: 0.4 MB.
• egui's bundled faces stay in the editor too, behind fallback-fonts: 1.4 MB. A game draws with its own fonts/ and the Source Sans 3 face the engine carries.
• Images decode as the seven formats a material and a sky read: PNG, JPEG, WebP, BMP, TGA, HDR and EXR.
• egui fills its glyphs with zeno, the rasteriser the engine's own text already links, in place of vello_cpu: 1.4 MB, and half the time per glyph.
• physics2d and physics3d each register one world, and [export] runtime = "2d" puts a game on its target's one-world template: web-2d is 17.1 MB raw and 4.7 MB brotli.
• The export refuses that template for a game whose scenes or scripts use the other world.
• The examples on this site play on the template their [export] runtime names.
• --keep-sources still ships source, for an editor that shows the code; only a build with compile runs such a pack.
