/* Gunship — interface styles.
   Look: a cold, monochrome instrument panel. Black and white do the work; color only carries meaning
   (red = hostile or critical, cyan = friendly, amber = marked target). Titillium Web for everything:
   names, headings, uppercase labels and readouts, hairline rules, corner brackets only on FIRE and Deploy.
   The fonts are bundled in /fonts (SIL Open Font License), so the game stays offline and loads nothing from other sites.
   Layout is mobile first: full-width cards, list rows and bottom sheets, touch targets of 48 px or more.
   One dark look on purpose (it is a night-vision display), so there is no light theme. */
