Derive the gem-blue palette with OKLCH tonal and complementary-color
rules while preserving acrylic opacity, blur and surface hierarchy.
Darker focus tokens exposed stacked field rings, fallback outlines and
persistent basemap selection rings. Keep fallback focus styles in the
base layer and use one themed field boundary or inset card stroke.
Preserve keyboard focus, invalid states and native input semantics.
Add browser regression coverage for pointer and keyboard focus, all
basemap presentations, narrow layouts and rendered contrast.
Validation in an isolated checkout: pnpm lint, pnpm typecheck,
pnpm test (393 tests), focused browser suites and pnpm build.
Unify the Agent history extension with the header acrylic surface, preserve the full conversation body, and consolidate shared control and status styling.
Restore map flow and SCADA controller behavior, remove obsolete rendering paths, and extend regression coverage. Button press coverage now releases outside the target so state assertions cannot accidentally toggle the control.
