Modules
LanternUI — a dev-tool-native, open-source component system for Phoenix LiveView.
Native LiveView chart components — server-rendered SVG, minimal JS.
Pure geometry helpers for LanternUI charts: linear scaling, "nice" axis ticks, and SVG path building.
Class-string composition for LanternUI components.
Path breadcrumb for file/tree navigation (a lantern-ui extension — Fluxon has no equivalent).
Buttons — Fluxon-compatible API, shadcn-caliber styling.
A month-grid calendar primitive — the pane the date pickers compose.
Checkbox with label, description, and error states.
Date/time pickers — Fluxon-compatible API composed from LanternUI primitives.
A segmented, directly-editable date/time field — the trigger primitive the
date pickers compose (HeroUI-style: 2 / 3 / 2026, 8:45 AM).
Dropdown menu on the shared overlay runtime (anchored placement, focus return, Escape/outside dismissal, arrow-key item navigation).
Quiet empty/zero state for tables, lists, and panels (a lantern-ui extension — Fluxon has no equivalent).
Form chrome — label, error, and a Fluxon-compatible input.
A small, curated inline-SVG icon set (Heroicons outline paths, MIT).
App-shell layout — a fixed, collapsible sidebar beside a main column with an optional topbar. The core navigation chrome for a dev-tool or app, and a drop-in-shaped replacement for a Fluxon sidebar layout.
Modal dialog on the shared overlay runtime (focus trap, Escape/outside
dismissal, prefers-reduced-motion-aware fade).
