Button:
- :icon-left, :icon-right props for buttons with leading/trailing icons
- :icon prop for icon-only buttons (square padding via .btn-icon class)
- Icon size scales with button size (sm→sm, md/lg→sm/md)
Alert:
- Auto-assigns variant-specific icons (circle-check, alert-triangle,
alert-circle, info) per variant
- :icon-name prop to override default, false to suppress
- Layout restructured with .alert-icon + .alert-content wrapper
Badge:
- :icon-name prop adds a leading icon before text
- .badge-icon CSS scales icon to match badge font size
Form input:
- :icon-left and :icon-right props on form-input
- Wraps input in .form-input-wrap with absolutely-positioned icon spans
- Padding adjusts automatically via .form-input--icon-left/right
All three dev targets (hiccup, replicant, squint) updated with demos.
Instead of rendering error messages as `<small class="form-error">`
below inputs, errors now display as a circle-x icon inside the input
area. Hovering the icon shows the error text in a danger-styled tooltip.
- Wrap children in `.form-field-control` when error is present
- Use existing tooltip + icon components for the error indicator
- Add CSS for positioning, padding-right offset, and danger color overrides
- Update tests to match new structure
- Add pre-commit tmux server check instructions to AGENTS.md
When :href is provided, the button renders as <a> instead of <button>,
enabling navigation links with full button styling.
New :link variant renders as a minimal text link (underlined, accent
color, no background/padding) — works as both <button> and <a>.
CSS includes reset styles for a.btn (removes default link decoration)
and preserves underline for a.btn-link.
