Incise 1.12.13

Markdown release: linting against a platform dialect, richer source styling, and a visual editor.

Markdown profiles + linter — Edit ▸ Lint Markdown for ▸ picks a target dialect (Looker Markdown files, GitHub-Flavored, CommonMark). Constructs the target won't render get an amber squiggle; hover one to see why. View ▸ Markdown Issues (⌘⇧M) lists every finding and jumps to it.

Rich Markdown styling — headings render larger and bold, bold is bold and italic italic, code sits on a faint slab, links are coloured, and the syntax markers (#, **, backticks, bullets) dim so prose stands out from its markup. View ▸ Rich Markdown Styling.

Visual Markdown editor — View ▸ Markdown Editor opens an editable pane beside the source, bound to the active profile: its schema, serializer, and toolbar all reflect the dialect, so it can only produce Markdown the target renders. The source file stays the record of truth. Documents using constructs it can't model open read-only rather than rewriting them.

Also — spell-check no longer flags URLs, autolinks, inline code, or link targets, and hovering a misspelling shows its corrections. The file tree's font setting is labelled more clearly.
