chart_sparkline

Compact in-line trend strip from a NumberSeries, showing only the most recent values that fit the slot. Defaults to block-glyph bars; switch to style = "line" for a single-row Braille line, and zero-value columns get a baseline tick so sparse stretches read as data instead of padding.

Theme tokens

Overridable via the [theme] section of your dashboard config.

Key	Description
text	Primary body text colour for plain renderers (text_plain, text_ascii, list_plain, animated_typewriter). The top step of the chrome ladder — brighter than text_secondary, reads as diffuse daylight on the ocean surface. Set text = "reset" to inherit the terminal's own foreground instead.
text_dim	Barely-visible chrome text: timeline date prefixes, empty-state placeholder, clip hint. Replaces the old Modifier::DIM usage — set an explicit colour so rendering stays consistent across terminals (some render DIM as invisible, some as a no-op).
