FX.31 ModelCraft: Play turns into Pause while an animation plays, and Space toggles it

Reported 2026-10-20: the Play button stays a triangle while the animation runs (it acts as stop); the reporter asks for a Pause state, matching the timeline, and for Space to play and pause while the timeline is open. Untested.

Built 2026-11-05 (model-fix-09), in /lab. The timeline's own Play button already turned into Pause while playing (since 0.6); what stayed a triangle was the Animate workspace's toolbar Play (a second button, and Stop beside it). Now it shows Pause (icon, word, pressed) while the animation plays and a second click pauses; Space plays and pauses while the timeline is open (not when a button has the focus, not while a tool runs; with the timeline closed Space is still Select); the new command Play or pause the animation (camera.play) can be given any key in a style of your own. Tests: browser-fix09.mjs 'FX.31' (real keys and clicks) and test-fix09.mjs. Help: animation topic.
