v2.82.0

Self-hosted ZenNotes server 2.82.0 with the pinned browser artifact web-2.82.0-web.hef00e9245b876c04 (built from ZenNotes/zennotes 6ea4775a, the v2.82.0 release commit).

What changed for self-hosters, all in the browser app the server hands out:

• New Kanban columns can carry a color. C on a column, its header's menu, a card's menu or Set Board Column Color in the palette pick from the theme's palette, and the color reaches the matching chips in the Table view.
• A hidden sidebar can always come back without a keyboard. With Note tabs off, a note's header and Tasks now hold a button to show it again. Before, only the shortcut did, and that left a touch screen stuck.

Import from Notion and Obsidian and opening a vault's folder are desktop features, so they do not appear here.

No Go changes: vendorHash is unchanged.

Verification before publication: the release workflow (run 41713344183) built the five binaries from 5dfaea1 after go, docker and nix checks passed on #66; every binary matches SHA256SUMS, and the manifest.json asset is byte-identical to the pin. The exact server binary with this package was run on a scratch vault in a browser: the sidebar fix with Note tabs off on a note and on Tasks, and the palette offering no import or file manager commands. The column colors were walked on the phones and the desktop with this core, not on this web build.

Docker: adibhanna/zennotes:2.82.0, 2.82 and latest are published from this tag by the repository's Docker publisher (linux/amd64 and linux/arm64, one digest).
