- Introduce VegaResearchChoiceScreen for ambiguous tech selections: when
a player completes research that opens a 2+ way choice rung, they're
prompted before the turn report to pick their next technology.
- Add VegaDelaunay.js (Bowyer-Watson Delaunay triangulation) and use it
in VegaStarMap to draw "controlled space" corridors/fills between the
player's own colonized stars instead of a blanket radius.
- Improve star map UX: stagger docked fleet markers per-star, add
PAN_SLACK so edge stars can be dragged out from under the side panel,
and show colony info bars at mid-zooms with text only at near-zoom.
- Add `closable` option to modalShell so forced-choice screens can
suppress the ✕ button.
- Export buildVideoPanel from VegaResearchScreen for reuse by the new
choice screen.
- Update artwork JSON: rrashaa and cerebrai audience videos now use
species-specific clips; add intro-human.mp3 and new video assets.
- Add tests for openResearchChoices and pendingResearchChoices filtering
logic in verifyMasterOfVega.js.
