* editor/get-styles + editor/set-styles — the GBS CSS store, symmetric with |
| 3 |
* editor/get-context (HTML) and editor/get-scripts (JS). |
| 4 |
* |
| 5 |
* READ (get-styles) has two scopes: 'page' (this page's payload + the SELECTED |
| 6 |
* block's ownership styleContext) and 'global' (the site-wide option). Pure reads. |
| 7 |
* |
| 8 |
* WRITE (set-styles) is GLOBAL-scope ONLY — the header/footer / site-wide CHROME |
| 9 |
* WP OPTION (read via GET /global-styles/user-css, written via the shared |
| 10 |
* /global-styles/sitewide merge route — IMMEDIATE + site-wide, not reversible by |
| 11 |
* discard). The former scope:'page' WRITE (an IMMEDIATE `/global-styles/save` |
| 12 |
* write to this post's `spectra_blocks_pro_gs_user_css` meta) was REMOVED: it |
| 13 |
* persisted a per-block style edit to the DB before the user Saved (no undo) and, |
| 14 |
* on a SHARED gs- class body, silently restyled every section carrying it. All |
| 15 |
* per-block styling is now a utility className via editor/apply-change (editor |
| 16 |
* state, committed on Save). scope:'page' here is rejected, defensively. |
| 17 |
* |
| 18 |
* The global write does READ → MERGE only the touched buckets → WRITE (never |
| 19 |
* full-replace, so importer chrome + user classes survive), then RENDERs the |
| 20 |
* merged payload via the SSOT GenCssRenderer (REST /global-styles/render) and |
| 21 |
* injects it into the canvas iframe for live paint. |

| 96 |
// The OWNERSHIP MODEL: a visual property is set by ONE of three layers, in |
| 97 |
// descending CSS specificity — a block ATTRIBUTE, a GBS CLASS body, or the |
| 98 |
// block DEFAULT (DEVELOPER-INSTRUCTIONS §5.1). To change a property you edit |
| 99 |
// its current OWNER (update the existing class, don't stack a new one; clear a |
| 100 |
// block attr that pins it). This resolver answers "who owns each property" so |
| 101 |
// the agent never hand-resolves specificity. It does NOT compute the exact |
| 102 |
// frontend winner (the editor canvas inverts utility-vs-gsClass specificity, |
| 103 |
// and utilities are JIT-compiled, not in the GBS payload) — `effective` is the |
| 104 |
// rendered truth and the agent's verify-iterate loop corrects any mis-guess. |
| 105 |
// The property map is small and explicit ON PURPOSE: it is this tool's job. |
| 106 |
// `prop` is the kebab CSS property — it doubles as the GBS-body key (bodies are |
| 107 |
// kebab, e.g. `font-size`) and the getComputedStyle key. Only `attrs` (the |
| 108 |
// block-attribute path(s) for that property) is non-derivable. |
| 109 |
// NOTE: ownership matches the EXACT property name — the shorthands `padding` / |
| 110 |
// `margin` resolve against a rule's `padding` / `margin` declaration, not a |
| 111 |
// longhand-only rule (`padding-top`). This system's utilities + gs- bodies write |
