An Island at 44px holding 36px tool buttons, each with a subscript shortcut.
Appears only when a tool or element is active; 12px legends over segmented rows.
Same white ground, same 8px radius, same three-layer shadow. No border.
Buttons and tool icons are 36px at 8px; menu items 42px at 6px. Rest is transparent, hover is the violet-tinted #f1f0ff, and the selected state is #e0dfff with a #6965db glyph. Fields sit on #ececf4 behind an #ebebeb border that steps to #5753d0 on hover and #4440bf on focus.
Motion in the shell is limited to short colour and background fades on hover and active; the canvas itself is redrawn imperatively by rough.js (the Sloppiness control is its roughness parameter) rather than animated in CSS. No keyframes, scroll effects or animation library in the chrome.
