v1.5.2

[1.5.2] - 2026-08-25

Fixed

• Colors written in any CSS notation other than the legacy rgba(r,g,b,a) form (hex, rgb(), hsl(), CSS named colors, and the modern space/slash rgba() syntax) — including individual stops inside linear-gradient()/radial-gradient() values — are now canonicalized to rgba(r,g,b,a) on every expand (create_page/update_page/add_section/patch_page/validate_page) across all color-bearing keys (color, background, backgroundTxt, borderColor, overlay, and other *color* keys), fixing the Webcake editor's color and background traits showing black instead of the intended color.
• A styles.color/backgroundTxt/borderColor value set on only one breakpoint is now mirrored onto the other breakpoint on save, since the editor's color traits read one breakpoint at a time with no desktop/mobile fallback and previously showed (and could save) black on the breakpoint missing the value.

Changed

• validate_page now warns when a color-bearing styles/config value cannot be converted to rgba() (e.g. var(--x), color-mix(...)), naming the offending element and a patch_page fix.
• The generation guide and page-schema.json descriptions for styles.color/background/borderColor/overlay now document the rgba()-only requirement, the both-breakpoints requirement, and the automatic conversion/mirroring behavior.
