|
|
* Registers the peptide_topic taxonomy for linking blog posts to peptides.
|
|
*
|
|
* What: Defines the `peptide_topic` taxonomy attached to the post CPT.
|
|
* Non-hierarchical, uses peptide slugs as terms (e.g., 'bpc-157', 'tb-500').
|
|
* Enables the Related Articles feature for blog posts tagged with a peptide topic.
|
|
* Who calls it: PR_Core::init() on plugins_loaded.
|
|
* Dependencies: None.
|
|
*
|
|
* Ownership: As of v0.3.0, PR Core owns `peptide_topic` taxonomy.
|
|
* Registration is guarded by `taxonomy_exists()` so deploy order does not matter.
|
|
*
|
|
* @see ARCHITECTURE.md — Taxonomy specification.
|
|
* @see CONVENTIONS.md — Taxonomy ownership rule.
