| 19 | * Typed accessor surface over a per-element {@see CascadedValues} bag |
| 20 | * per `docs/plans/contracts.md` §1D.5. Each getter narrows the |
| 21 | * underlying `Value` to the type(s) the property's grammar permits; |
| 22 | * properties not explicitly set fall back to the registry's initial |
| 23 | * value (via `CascadedValues::get()`). |
| 24 | * |
| 25 | * The class is intentionally a thin wrapper — it adds no caching or |
| 26 | * computation of its own. The cascade resolves percentages, inherits |
| 27 | * values, and produces the initial-value fallbacks; ComputedStyle |
| 28 | * just exposes them with PHP-static-analysable signatures so |
| 29 | * downstream consumers (the box generator, painter, SVG renderer) |
| 30 | * don't have to type-check every `?Value` themselves. |
| 31 | * |
| 32 | * **Type narrowing fallback.** When a property's parsed value doesn't |
| 33 | * match its declared type (an invalid `font-weight: foo` slipping |
| 34 | * through), the getter returns the property's initial value instead |
| 35 | * of throwing — keeping the accessor surface infallible at the cost |
| 36 | * of swallowing parser errors that should have been caught earlier. |
