From 8eb40337ea274f3a3622299e7f4333b7f2816754 Mon Sep 17 00:00:00 2001 From: Maroun Najjar <60901592+thecolormaroun@users.noreply.github.com> Date: Tue, 10 Nov 2026 13:38:05 -0800 Subject: [PATCH 1/2] refactor(design): drop Twombly from micro-branch; the local board is the only canvas Twombly is a paid third-party product, so it comes out of Stack. - mb.py: remove the Twombly adapter, its version pin, port and privacy flags, `feedback` (canvas comments and focus) and the Excalidraw scrub, which only existed to pass Twombly's secret check. `--canvas` is gone. `publish` now starts or reuses the board and returns its URL. State written by older versions loads cleanly; unknown config keys are dropped. - Kept: the Design Studio preset, per-origin board frames (r-t.localhost), `--view`, `--entry` and `--localize`. - Docs: references/twombly.md deleted; SKILL.md, setup recipes, troubleshooting and the Design Studio reference rewritten for the board. The plan gets a dated note instead of a rewrite. - Tests: Twombly tests removed; new tests for the board URL on publish, loading old state, and a ban on "twombly" anywhere under skills/.

Plain `init` writes the cleaned state to disk. The test builds a Twombly-era state with a round, two takes and old frame data, and checks the file on disk.
