FX.55 BimCraft: typing LEVEL does nothing and the ribbon has no Levels button; optional side-panel accordion with a lock (setting, default off)

a Discord member, 2026-11-05 (working in /lab with the drafting ribbon): the help describes the Levels panel, but typing LEVEL on the command line said Unknown command and no ribbon button led to it.

Built (/lab, a Discord member): the command line takes LEVEL, LEVELS, STOREY, STOREYS (opens Add levels…); a Levels button sits in the Home > Levels group (Drafting ribbon), the Architecture > Model group (Ribbon) and the Home menu (model.levels in input-bimcraft.js). The left/right panel's collapsible sections (Find, Quantity totals, Checks, Clash …) close each other so the one you opened has the focus when Settings > BimCraft > Side panels is on (default OFF, owner's call 2026-11-05); a lock beside each caret keeps one open, remembered on this device (panel-focus.js). Test: tools/bimcraft-test/browser-levels09.mjs, 15/0. Not in the Docked/Duncan layouts' own tool sets (the docked ribbon already had Level). New strings are English only until the next language sync.
