Five of six items from user feedback (Contact Form email delivery split
into a focused, live-tested follow-up):
- Social Links: add Spotify + Twitch (FA 4.7.0 already ships both glyphs).
- Features Grid: per-feature icon/image toggle (upload + URL) and an
optional button (text + url); render, settings, and HTML export updated,
backward compatible with existing icon-only features.
- Header: seed the default header with a Navbar (logo + Home/About/Services/
Contact) so new sites open with an editable menu-with-links instead of an
empty header zone. Adds a vitest guard that the seed deserializes and
exports a real <nav>.
- Canvas: slim the empty header/footer placeholder from a padded band to a
thin hint line so an empty zone no longer reads as a stray spacer.
