feat: add fonts: asset key to bring fonts into the deck contract#160
Merged
Conversation
Closes #159. Adds a fonts: frontmatter key (with deck-adjacent fonts/ auto-detect) that resolves to a directory or file. peitho then copies the fonts verbatim into the build output, the PDF export workspace, and the present cache — so site, PDF, and presenter all render with the same web fonts regardless of host environment (fixes WenQuanYi Zen Hei fallback on Linux CI). The five-lens invariants held: symlinks rejected symmetrically for source and directory entries, deterministic filename order, dotfile filtering in watch mode, always-clear dist/fonts/ so a removed fonts: key doesn't leak stale bytes into publish, and recursive watch expansion for nested subdirs like @fontsource/inter/.
