+/**
+ * Tactical Theme for Navi
+ *
+ * Military topographic map meets NVG-compatible night display. Dark olive/charcoal
+ * base with muted sage greens for text — readable but low-signature. Subdued amber
+ * for roads and primary actions (amber preserves night vision better than blue/white).
+ * Danger in muted red. Low contrast by design — intentional for night use.
+ *
+ * Water is dark blue-gray, land is dark olive. Contours are PROMINENT in olive-brown —
+ * this is a topo-first theme. The feel is a ruggedized field tablet displaying a
+ * mil-spec moving map.
+ *
+ * Designed for field use and eventual ATAK/iTAK integration.
+ * Functional, not decorative.
