* editor/get-scripts + editor/set-scripts — typed read/patch over a BLOCK's |
| 3 |
* `spectraCustomJS` attribute (the per-block JS store). `spectraCustomJS` in |
| 4 |
* post_content is the single source of truth for page behaviour — Spectra Pro's |
| 5 |
* BlockJsCompiler renders it once at wp_footer (spectra-blocks-pro #165), |
| 6 |
* superseding the removed per-page `_spectra_blocks_page_scripts` meta. |
| 7 |
* |
| 8 |
* SESSION-SCOPED BY DESIGN (the apply_change philosophy): reads come from |
| 9 |
* `core/block-editor` getBlockAttributes (the live editing session, incl. |
| 10 |
* unsaved edits) and writes go through updateBlockAttributes — the block's JS |
| 11 |
* updates in the session immediately, is DISCARDED if the user discards the |
| 12 |
* session, and persists only on Save. A REST write here would race the open |
| 13 |
* editor's copy and mutate before save — never do that. |
| 14 |
* |
| 15 |
* Target a block by `clientId` (default = the page root container, the first |
| 16 |
* top-level block — page-wide behaviour). The stored code is raw JS; the |
| 17 |
* renderer wraps it in an IIFE and resolves the `_current_block_` token to the |
| 18 |
* block's scope class. |
