Theme simplification (theme/theme.go):
- Remove Purple and BorderHover fields from Theme struct — neither was
referenced in the new tab renderers, reducing per-theme boilerplate
from 14 to 12 color definitions
Component extraction (components/):
- Move Sparkline() and BarChart() from card.go to new chart.go, giving
visualization components their own file as complexity grows
- card.go retains MetricCard, ContentCard, LayoutRow, and CardInnerWidth
which are layout-focused
- New chart.go: Sparkline (unicode block chars) and BarChart (multi-row
with anchored Y-axis, optional X-axis labels, dynamic height/width)
- New progress.go: ProgressBar component with customizable width, color,
and percentage display — used by rate-limit and budget views
Status bar and tab bar updates:
- statusbar.go: adapt to simplified theme struct
- tabbar.go: adapt to simplified theme struct
Implement the theming layer for the interactive dashboard:
- tui/theme/theme.go: Theme struct with 14 semantic color roles
(Background, Surface, Border, BorderHover, TextDim, TextMuted,
TextPrimary, Accent, Green, Orange, Red, Blue, Purple, Yellow).
Four built-in themes:
* Flexoki Dark (default): warm, low-contrast palette designed for
extended reading. Teal accent (#3AA99F) on near-black background.
* Catppuccin Mocha: pastel warm tones with blue accent (#89B4FA)
on dark surface (#1E1E2E).
* Tokyo Night: cool blue/purple palette with blue accent (#7AA2F7)
on deep navy (#1A1B26).
* Terminal: ANSI 16-color only for maximum compatibility — maps
all roles to standard terminal colors (0-15), works correctly
in any terminal emulator regardless of true-color support.
Global Active variable holds the current theme. SetActive/ByName
enable runtime theme switching from the settings tab and setup
wizard.
