// @history 1.1.0 — Reworked `CSSRGBintoComponents()` to better handle cases where the color is in the format `color(srgb ...)`. Changed how lightness_increase works so that it's a negative value when `color-scheme` is `light` and zero when `color-scheme` is neither `light` nor `dark`. Reworked `phb_color` so that the string it outputs uses the newer space separated `rgb()` parameters (https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/rgb#syntax)
