Features

Each page in this folder documents one feature and demonstrates it live. View the source on any of them for the markdown behind it.

Topic	What you will see
Wikilinks	`[[Page]]`, aliases, image embeds, transclusion, cross-tier behaviour
Callouts	Styled callouts and role-gated paragraph redaction
Images	`image:` frontmatter, cover discovery, social meta, compression
Bases	Filtered and sorted views over your vault: table, cards, list
Handlers	Inline `prefix:` and code-block transforms, with , `{{(empty)}}`, `gallery`, `download`, `foundry-install` and `fvtt-link` built in
Statblocks	D&D 5e creature statblocks from Fantasy Statblocks YAML
Role gating	`public`, `patron` and `dm` tiers, page and callout gating, the auth flow
Foundry integration	Building the vault into Foundry VTT, documents from `foundry.source`, player-visible pages
Passthrough files	Audio, video, PDF, EPUB and JSON files, gated per variant
Patreon login	Roles granted by Patreon tier
OIDC login	Single sign-on against any OIDC issuer, roles granted by email or domain
Math	$inline$ and `$$display$$` LaTeX, rendered at build time with KaTeX
Battlemaps	Layered, multi-level maps with a grid overlay and PNG export

Smaller features, without a page of their own:

Frontmatter dialog: the {} button in the top-right of any page with frontmatter shows the raw YAML in a copyable box.
Generated folder indexes: a folder without an index.md gets one, a Bases table of its contents with a list of subfolders above it. See Mossfoot/NPCs/index, Mossfoot/Items/index and Mossfoot/Lore/index.
Folder notes: with folder_notes: true in .vaults/settings.yaml, a note named after the folder it sits in is that folder's page, the convention Obsidian's folder-note plugins use. See Mossfoot/Decks, which is written as Mossfoot/Decks/Decks.md and served at /Mossfoot/Decks. An index.md wins if a folder has both.
Dark mode: the theme picker in the sidebar offers auto, light and dark. accent_color_dark and bg_color_dark in .vaults/settings.yaml set the dark palette; accent_color and bg_color set the light one.
Social meta: every page emits og:title, og:type and og:site_name. A page with a cover image also emits og:image and twitter:image, with a summary_large_image card.
Search: every variant ships its own _search-index.json. The search box in the sidebar matches substrings of titles, paths and body text, ranking title matches first.
Hover previews: desktop browsers preview a page on hover, fetching <path>.preview.json on demand. preview_mode selects the behaviour: normal (the default) shows a popover and navigates on click; sticky pins the popover open on click, with a "Go to page" link; none disables previews.
Backlinks: every page lists the pages that link to it in the right sidebar, computed at build time.
External links open in a new tab: links off-host get target="_blank" rel="noopener noreferrer".
Obsidian snippets: .obsidian/snippets/*.css ships as user.css, loaded after the default theme. When .obsidian/appearance.json exists, only the snippets it enables are included.
Page transclusion: ![[Some Page]] on its own line inlines that page's rendered body; ![[Some Page#Section]] inlines one section. See Wikilinks.
Sitemap and robots: with site_url set in .vaults/settings.yaml, the build writes sitemap.xml and robots.txt listing the default-role pages.
Schema migrations: vaults migrate applies pending vault layout changes when the CLI's internal format moves. --list shows what exists, --dry-run what would change.
