Harden UI layout for font scale and long strings

- Measure and cap the HUD target chip after each font-scale change; clip HUD top labels.
- Ellipsize long action-button labels so panels cannot grow past the viewport.
- Add accessibility/button layout assertions and refresh the gallery captures.
- Record the font/layout pass in TODO, docs, changelog and memory.

+## Font-scale and long-string layout
+
+The HUD scale is tested at its **0.75×** and **1.75×** bounds. HUD top/time labels
+clip instead of crossing into each other, and the target chip now measures the
+scaled target text: normal long names widen the chip, while an extreme synthetic
+name is capped at 420 px and ellipsized. Action-button labels use `clip_text` and
+ellipsis in `UiStyles`, so a 1.5–2× pseudo-string cannot push a panel beyond the
+viewport. The menu shell intentionally keeps its own fixed typography; the HUD
+scale setting only changes HUD text.
+
+Regression coverage lives in `test_accessibility.gd` (target-chip width/cap) and
+`test_ui_buttons.gd` (long action-label minimum width). The pseudo-locale
+translator workflow remains a 0.10.0 task; this pass uses deterministic long
+strings and the maximum supported HUD scale.

 ## Remaining audit work
 
 - Player-facing labels are now routed through `content/strings.en.json`; numeric
   values, empty-state clears and debug-only text remain in code by design.
 - Focus/hover/pressed/disabled states and keyboard/gamepad rings are recorded above.
-- Test long strings and 1.75x HUD font scale.
+- Long strings and 0.75×/1.75× HUD scale are covered above.
 - Capture every dialog/button state and run `screen_designs.py compare` plus the pinned judge.
