4. AtlasPanel and AtlasViewer now compose their title + hint from an
ImplantHeader child rather than hand-rolling them via draw_string, so the
D-169 "theme swap changes the implant hardware appearance" invariant
holds end-to-end. _refresh_screen_header() drives content per level and
on system navigation.
5. AtlasViewer exposes city_canvas_pos(), get_hovered_city(),
get_selected_city(), and get_overlay_defs() as public API — the marker
overlay no longer reaches into underscore-prefixed state, which is
especially important because viewer is an untyped var in the overlay.
6. KEY_N now consumes unconditionally while the viewer is visible, and
main.gd's global economics-monitor toggle is gated on
!HudGroups.is_app_active("implant/map/atlas"). Previously pressing N
without a selected city fell through and closed the fullscreen atlas as
a side effect.
7. OVERLAY_DEFS lives in AtlasViewer as the single source of truth.
AtlasOverlayBar reads the list via viewer.get_overlay_defs(), and
AtlasViewer derives _overlay_visibility / _overlay_locked from the same
table at _ready() — no more hand-maintained parallel lists, so the bar
and the guard in set_overlay_visible can't drift.
8. AtlasOverlayBar drops `class_name`: it now loads via
load("res://ui/implant/atlas_overlay_bar.gd") from AtlasViewer, the same
pattern AtlasPanel uses for AtlasViewer. _init(viewer_ref = null) keeps
the required-arg footgun off the editor's introspection path.
9. `star-map-data` make target added to regenerate
client/data/star_map_data.json from systems.db + wiki, and
`check-star-map` wired into pre-pr-validate + pre-pr-client so any
commit that touches the generator (or any downstream systems.db change
like server #839) fails pre-pr until the JSON is regenerated. The
terrain_reference data-availability dependency is no longer tribal
knowledge.
Also addresses review #15 (push_warning on unknown overlay id in
set_overlay_visible) and #16 (disabled always-on buttons drop handler
churn) as part of the same refactor.
