10	* Astra's Customizer colours, read from its settings rather than its slots.
11	*
12	* Astra keeps its Theme Colors as settings that point at a palette swatch
13	* (`var(--ast-global-color-N)`) or hold a custom colour, and its primary
14	* button colours as four settings that are empty until the owner sets them.
15	* `astra_get_option()` merges what the owner saved over Astra's defaults, so
16	* an untouched install reads its defaults and a customised one reads the
17	* customisation — the same values Astra's own dynamic CSS prints from.
18	*
19	* Empty button settings follow Astra's own chain, not a FluentCart default:
20	* background → Accent (`theme-color`), hover background → Link Hover
21	* (`link-h-color`), and each text partner → the colour that reads on its
22	* background.
23	*
24	* Verified against Astra 4.13.11.
