// HACK: lucide ships every icon inside a 24×24 viewBox where the path
// doesn't touch the edges — there's per-icon internal padding. The layout
// already places the SVG element's box on the rail, but the visible glyph
// inside the SVG sits inset by a few pixels (and the inset amount differs
// per icon — chevron-right paints only in the right half of its viewBox,
// regular tool icons paint roughly the full viewBox minus ~1 unit margin).
//
// Lucide has no viewBox knob, so the only way to nudge the visible glyph
// flush with the rail is a per-icon negative margin. Cosmetic; not exact —
// every lucide icon has slightly different padding and we're not measuring
// each one. Two buckets is the compromise:
// - LUCIDE_TOOL_ICON_NUDGE_LEFT: regular tool icons (path mostly fills
// the viewBox); needs ~1px left shift.
// - LUCIDE_CHEVRON_NUDGE_LEFT: chevron-right (path in right half of
// viewBox, and we scale it 1.3×); needs ~4px left shift.
// If we ever want this exact, the principled fix is a custom <Svg> wrapper
// with a tight viewBox per icon — see option (2) in the design discussion.
