 ## [Unreleased]
 
+### Changed
+- UIStrings YAML parser now handles arbitrary nesting depth and inline comments — adapts to copy team's restructured ui-strings.yaml with multi-level sections (relationship_states, health_values)
+- HUD uses new YAML keys: `hud.perception_mode_prefix`, `hud.time_prefix`, `hud.health` (empty prefixes display values directly)
+- Interaction prompt keybind hint ("E") hardcoded instead of loaded from YAML — keybinding is not copywriter text
+
 ### Added
 - UIStrings autoload with YAML-based UI string loading (#409) — minimal YAML parser, `get_text()` lookup with fallback-to-key
 - HUD and interaction prompt labels now loaded from `client/data/ui-strings.yaml` instead of hardcoded strings
