refresh_theme_controls() colored the divider and the ANSWER/KEY
TAKEAWAY captions, but it only ran on an actual theme toggle - never
at initial build. Confirmed live: the divider was invisible (default
white on a white card) and the captions rendered as plain body text
instead of the intended accent color until you toggled dark mode
once. Call refresh_theme_controls() once at the end of _build() so
the correct colors apply immediately, which also fixes the same
latent gap in empty_label's color.
