/** |

* Blocksy's Customizer colours, read from its theme mods rather than its slots. |
| 11 |
* |
| 12 |
* Blocksy keeps each semantic colour as a theme mod shaped |
| 13 |
* `['default' => ['color' => …], 'hover' => ['color' => …]]`, whose colour |
| 14 |
* points at a palette slot (`var(--theme-palette-color-N)`) or holds a custom |
| 15 |
* colour. Links, Base Text, Borders, Site Background and Buttons are separate |
| 16 |
* settings — the button is not tied to the link colour — so each role is read |
| 17 |
* from its own mod. |
| 18 |
* |
| 19 |
* A mod the owner never saved, or a sub-key missing from one, takes Blocksy's |
| 20 |
* own default for it, the same fill `blocksy_get_colors()` applies before |
| 21 |
* printing (inc/dynamic-styles/global/all.php). A colour saved as Blocksy's |
| 22 |
* "inherit" sentinel (`CT_CSS_SKIP_RULE…`) counts as unset the same way. |
| 23 |
* |
| 24 |
* Palette references are resolved through |
| 25 |
* `blocksy_manager()->colors->get_color_palette()` (see paletteValues()), and |
| 26 |
* always kept live: Blocksy Companion's dark mode redefines the palette |
| 27 |
* properties under `:root[data-color-mode*="dark"]`, which a bare hex would |
| 28 |
* never follow. |
| 29 |
* |
| 30 |
* Verified against Blocksy 2.1.57. |
