Theming

xyz.meowing.lattice.ui.theme.Theme holds the semantic tokens every widget default reads:

Token	Role
`accent`	primary accent (slider fill, switch on-state, checkmark, dropdown icon)
`accentSelection`	text selection highlight
`background` / `backgroundHover` / `backgroundPressed`	interactive surfaces
`backgroundDark` / `backgroundDisabled`	filled/disabled states
`surface` / `surfaceBorder`	panels and tooltips
`border`	default widget border
`text` / `textMuted`	foreground text
`track` / `scrollbar`	slider/switch tracks, scrollbars
`animFast` / `animNormal` / `animSlow`	shared animation durations (ms)

All colors are Int ARGB. Defaults match the original Vexel palette.

Tokens are read at construction time — widget constructor defaults evaluate Theme.x when the widget is created. So:

Theme.accent = 0xFF10B981.toInt()   // before building UI: everything green

Retheming a live screen means rebuilding it (see the "Cycle accent" row in the example mod). Explicit constructor arguments always win over tokens.
