/**
|
|
* Formats a generated system into a readable "dossier" for UI.
|
|
*
|
|
* Pure — no Phaser — so it's testable in Node and reusable anywhere a
|
|
* system needs describing (the HUD today; the star map, tooltips, saves,
|
|
* or a terminal UI later). Scenes stay thin: they render what this
|
|
* returns.
|
|
*
|
|
* The dossier is deliberately compact — the per-settlement and gate
|
|
* detail lives elsewhere (star chart, map, the content itself). What it
|
|
* carries: identity (type + star class), who controls the system, and
|
|
* how many are settled here.
|
|
*
|
|
* const report = formatSystemReport(content);
|
|
* // { title, subtitle, faction, population, status, statusColor }
|
|
* // title — the system name
|
|
* // subtitle — "Main Sequence system · star G"
|
|
* // status — "Faction: Apex · Pop ~1.2M" (or "… · Unclaimed")
|
|
* // The FACTION (data/factions.json — the roster's faction pass, on
|
|
* // content.faction): the controlling faction's label + color, or
|
|
* // Neutral (light gray) for the wild space + the neutral ring.
