Installation

$pnpm exec dgadd add ui/section-header

[Installs to]src/components/ui/section-header[Item]ui/section-header

dgadd is not public on npm yet. Until the first release, pack @diffgazer/add from the repository and install that tarball into this app, which is what puts dgadd on pnpm exec.

UI components require Tailwind CSS v4. Local copy mode imports src/styles/styles.css; package mode uses @diffgazer/ui CSS once packages are available.

Notes

Variant

The variant prop controls visual intensity. Default uses foreground color, muted uses muted-foreground, and accent uses the theme accent for a highlighted section label.

Heading Level

The as prop renders as h2, h3, or h4 (defaults to h3). Each level carries its own size, weight, and letter-spacing so the three read as a scale: h2 is the largest and tightest, h4 the smallest and widest-tracked.

Spacing

SectionHeader owns no outside margin. The layout that places the header decides the gap below it (for example mb-2 next to body copy, or a flex gap in a stacked panel).
