…s chrome are gone Response to "looks unprofessional … complete revamp … do not retain anything from the existing UI". The target switches from legacy-parity to spec-fidelity (docs/design/gantt3.html + composites2.html), and the old surface is deleted rather than gated. Canvas (ds/gantt): weekend and holiday shading now spans the full canvas height instead of the 44px axis strip, with the today rule continuing down the rows; the axis becomes the spec's two 28px tiers; phase rows are tinted across both panes; the tree pane is the spec's 392px name+dates two-column pane (duration and working days live in each bar's accessible description, not columns); the toolbar is the spec's segmented zoom radiogroup plus page actions and a live row count; a legend strip lists only the marks the plan actually draws. Chrome: the top bar gains a ds ProjectSwitcher (open/create/rename/ delete in one dialog — AppShell grows a projectSlot); views are ds Tabs; every tool action is a labelled ds Button in the canvas toolbar — no unlabelled icon strip. Editing survives the demolition: Enter or double-click on any bar opens the store-wired Edit Phase/Task modals, which the legacy canvas reached by double-click. Deleted (~6,300 lines of old UI): GanttCanvasV3 and its internals (HeatmapPhaseBar, MobileGanttView, ResourceDrawer, ResourceIndicator, ResourceRowMemoized, deletion-impact modals, dead-write TaskResource/ResourceAllocation modals), Tier2Header, ProjectTabNavigation, ViewModeSelector, UnifiedProjectSelector, ProjectMetrics, the ?canvas= strangler flag, and the two file-regex "visual compliance" suites that pinned the old Apple-HIG design. Known follow-ups: the orphaned-resource repair tool (lived in the deleted resource side panel) needs a ds home inside the Team surface; the architecture page's team sidebar is still old-styled inside. Verified: tsc, lint, 1776 unit tests (count drops with the deleted legacy suites), fresh production build with all 23 bundle budgets green, and the redesigned canvas render-checked in Chromium against the spec (segmented zoom, two-tier axis, full-height shading, tinted phase rows, labelled bars, legend).
