/** |
| 3 |
* Pro_Audit — scans the current Free configuration + cache stats and |
| 4 |
* surfaces Pro features that would specifically help THIS site. |
| 5 |
* |
| 6 |
* Powers the dashboard's "Run Pro audit" button. The point isn't to |
| 7 |
* list every Pro feature; it's to make each suggestion personal |
| 8 |
* ("Cache hit ratio is 38% → Pro Recommendations would tell you why") |
| 9 |
* so the user converts because Pro solves a problem they actually |
| 10 |
* see, not because we shouted "BUY NOW." |
| 11 |
* |
| 12 |
* Pure read-only. Returns an ordered list of suggestions: |
| 13 |
* |
| 14 |
* [ id, severity ('high'|'med'|'low'), reason, fact ] |
| 15 |
* |
| 16 |
* - id → matches a key in PRO_FEATURES (the React catalog), |
| 17 |
* so the panel renders title/body without duplicating |
| 18 |
* copy here. |
| 19 |
* - severity controls sort order + visual tone. |
| 20 |
* - reason → one-sentence explanation specific to this site's |
| 21 |
* state. Already-baked numbers/percentages so the |
| 22 |
* React side just prints it. |
| 23 |
* - fact → optional shorter inline stat (e.g. "38%") for the |
| 24 |
* result card's chip. |
| 25 |
* |
| 26 |
* Adding a rule: drop another `if (…) $out[] = …` block in run(). |
| 27 |
* Rules are independent — keep them small + concrete + factual. |
