Prototype .spd (Supernote Atelier) file support - #137
Merged
Conversation
Adds a minimal read-only viewer for .spd files (Supernote Atelier app), built on supernote-typescript's SupernoteAtelier parser (philips/supernote-typescript#33). Registers the 'spd' extension to a new SupernoteAtelierView that flattens every layer with toCompositeImage() and shows the result as a single image — no page concept, so none of SupernoteView's zoom/find/thumbnail toolbar or embed support yet. sql.js's wasm binary is embedded into the bundle via esbuild's binary loader (esbuild.config.mjs) rather than fetched/read at runtime, so it works the same on desktop and mobile without a locateFile() callback. Points the supernote-typescript submodule at a local merge of PR #33 (worktree-spd-parser) onto main, pushed to spd-prototype-merge-main so the pinned commit resolves for anyone cloning this branch. Closes #136.
supernote-typescript#33 (SupernoteAtelier/.spd support) has since merged into that repo's main branch (published to npm as 0.5.2, though that repo doesn't have a corresponding git tag yet). Repoints the submodule at upstream main directly, replacing the throwaway local merge of PR #33 onto main that was pushed to spd-prototype-merge-main as a workaround while the PR was still open.

Summary
Prototype for #136: a minimal read-only viewer for
.spdfiles (theSupernote Atelier app's format), built on top of
supernote-typescript#33's
SupernoteAtelierparser.spdextension to a newSupernoteAtelierView(
src/atelierView.ts) — opens the file, callstoCompositeImage()toflatten every layer, and shows the result as one image.
SupernoteView(the.noteviewer):.spdhas no page concept, just layered tiles on one canvas, so there'sno zoom/find/thumbnail toolbar, no embed registration
(
![[file.spd]]), and no vault-writing commands yet.sql.js's wasm binary is embedded directly into the bundle viaesbuild's
binaryloader (esbuild.config.mjs) instead of beingfetched/read at runtime, so it works the same on desktop and mobile

0.5.2, though that repodoesn't have a corresponding git tag yet).
