+; Text-object queries for SiSU Spine markup.
+;
+; Capture conventions follow nvim-treesitter/textobjects:
+;   @<thing>.outer  -> select including delimiters / surrounding whitespace
+;   @<thing>.inner  -> select content only
+;
+; Hosts that consume these (Neovim's nvim-treesitter-textobjects, Helix,
+; Emacs treesit) bind keys such as `af` / `if` to .outer / .inner.
+
+; =================================================================
+; Headings (sectioning units)
+; =================================================================
+; A whole heading line is a "section header" object. Heading sections
+; (the heading plus its body content up to the next heading of equal or
+; higher level) are not directly expressible in tree-sitter without
+; additional grammar work; hosts can synthesise that from these captures.
