+## author: xAI (grok build), ported by Anton

+## blurb: The GrokDay theme from grok build's TUI: light counterpart with deepened accents.
+
+# GrokDay — neutral light gray base with deepened accents.
+#
+# Ported from grok build's TUI theme:
+#   xai-org/grok-build
+#   crates/codegen/xai-grok-pager-render/src/theme/grokday.rs
+#
+# Light counterpart to GrokNight: same hue family, darkened for contrast on a
+# light background. background is grok's bg_base, the surface the TUI actually
+# paints; bg_terminal (#f5f5f5) is for terminal-output blocks and is unused.
+# cursor is accent_user, which grok itself sets over OSC 12 on startup.
