Add the base color mappings to the Shadcn stylesheet.

With examples enabled and Shadcn selected, the add-on replaces the base stylesheet. Tailwind therefore cannot generate utilities such as bg-header-bg and border-chip-line. Header backgrounds disappear and borders use the Shadcn fallback color.

Suggested fix

 @theme inline {

lines 36 - 38:
Add the missing base palette mappings to the Shadcn stylesheet’s @theme inline
block, including header-bg and chip-line, so Tailwind can generate the
corresponding utilities. Preserve the existing sea-ink mappings and align the
added mappings with the base stylesheet’s theme variables.
