+- The WORLD MAP now fills the entire available area of its tab (#36): in wide mode (pinned viewport, #21) the OPERATIONS Tabs are a full-height flex column and the world-map panel flexes to the bottom of the pane — the chart SVG sizes to the measured container instead of the old fixed 380px height, so there is no internal scrollbar on this tab at any window size. The scene keeps its viewBox and scales with the pane on resizes (pan/zoom stay accurate; re-fitting after a resize is intentionally not done). Narrow mode keeps the fixed fallback height since the page scrolls naturally there.
+- e2e: the #31 spec no longer relies on WORLD MAP's overflow to force scrolling — it now switches to SHIP SYSTEMS, whose six always-present stacked system cards deterministically overflow the shrunk 1280×560 pane (waiting for the HULL card first), and asserts the same pinned tab bar.

 ## v0.9.9 — 2026-09-29 11:21
 - The WORLD MAP chart is now a force-directed graph (d3-force) with pan + zoom (d3-zoom), replacing the hand-rolled static NodeGraph render (#28): nodes settle into a dynamic layout seeded from the API coordinates and visibly rearrange after every jump, then auto zoom-to-fit so the whole network stays framed in the chart box. Wheel/drag pans and zooms the scene; only systems adjacent to the current one remain clickable (same `role=button` + name contract as before), all nodes lock while a jump is in flight, and a real pan's trailing click never triggers an accidental jump. Jump flow (`POST /api/jump`, turn counter, `onJumped` refresh from #30) is unchanged; the now-orphaned hand-rolled `NodeGraph` component (world map was its only consumer) is deleted.
