7/// A title in a document (section titles, block titles, document title, etc.).
8///
9/// `Title` is a newtype wrapper around `Vec<InlineNode>` that provides convenient
10/// access to inline content. Titles can include formatting, links, and other inline
11/// elements.
12///
13/// # Accessing Content
14///
15/// `Title` implements `Deref<Target=[InlineNode]>`, so you can use slice methods directly:
16///
17/// ```
18/// # use acdc_parser::{Title, InlineNode};
19/// let title = Title::new(vec![/* inline nodes */]);
20///
21/// // Iterate over inline nodes
22/// for node in &title {
23///     // ...
24/// }
25///
26/// // Check if empty
27/// if title.is_empty() {
28///     // ...
29/// }
30///
31/// // Access by index (via deref)
32/// if let Some(first) = title.first() {
33///     // ...
34/// }
35/// ```
36///
37/// # Serialization
38///
39/// Serializes as a plain JSON array of inline nodes for ASG compatibility.
