/* Civ & Spire UI kit (HA 5631) — the ONE source for every component skin. Screens (style.css, v3.css, loadscreen.js,
   lobby.html) only lay things out; how a panel / button / tab / row / meter / chip / tooltip / modal / sheet / top bar
   LOOKS lives here.
   CIV 6 (transcribed, Base/Assets/UI): structure + frames + textures + meters + tooltip format + type hierarchy.
     textures  art/civ6ui/* (tools/civ6-ui-assets.py from UI_Controls/UI_HUD .blp); 9-slice insets from Civ6_Styles.xml
     type      body = Myriad Pro Semibold 14-16 (FontNormal*), numbers Myriad Bold; text 208,212,217 (TabFont Color0)
     tooltip   Controls_Tooltip light box, ink 5,29,51 (TTText), title / stats / cost / description blocks
     buttons   Controls_Button (Grid9MainButton), Controls_Confirm (Grid9ConfirmButton) for the one primary action
     rows      ProductionPanel_ChooserButton, icon left, name, turns-left big on the right, cost under it
     meters    CityPanel_MeterBacking + CityPanel_ProductionMeter / CitizenMeter (+ the Small variants in rows)
     panels    CityPanel_StatPanel navy gradient, bronze rim; modal = Controls_WindowFrame ornate frame
     top bar   TopBar_Back strip, yield chips = TopBar_YieldBacking colours (TopPanel.xml), Civ font icons
   SPIRE (accents only): gold-ink headings in Kreon small caps (StS2's UI face), the gold rim tone, the StS2 click/hover
   sfx (sfx.js 'ui_click'), card/relic/character art inside the chrome. */
