Implement shared UI components used across the dashboard tabs:
- tui/components/card.go: Three components:
* MetricCard: bordered card with label (muted), value (bold), and
optional delta (dim) — used for the dashboard's top-level KPIs.
* MetricCardRow: renders N cards side-by-side using lipgloss
horizontal join, auto-calculating card width from available space.
* Sparkline: theme-colored Unicode block sparkline (8-level,
auto-scaled to series max). Used in Dashboard and Trends tabs.
* ProgressBar: filled/empty bar (accent + dim) with percentage
label. Used in the Budget tab for plan-relative spend.
- tui/components/statusbar.go: Bottom status bar with left-aligned
keybinding hints ([f]ilter [?]help [q]uit), current filter info,
and right-aligned data age indicator. Padding auto-fills to
terminal width.
- tui/components/tabbar.go: 10-tab navigation bar split across two
rows (Dashboard/Costs/Sessions/Models/Projects on row 1,
Trends/Efficiency/Activity/Budget/Settings on row 2). Each
inactive tab highlights its keyboard shortcut letter with [bracket]
notation. Active tab renders in accent color. Settings uses 'x'
as its shortcut (not present in the name, so appended). TabIdxByKey
maps key presses to tab indices.

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.
