/*
 * Tailwind palette remap — spec 001 (revised): keep the existing templates and Tailwind classes,
 * change identity and accessibility underneath. Tailwind v4 reads colors from these custom
 * properties; unlayered declarations here override its @layer theme defaults.
 * Light (default): blue/indigo = IPL globe blue, purple/violet = globe highlight sky; tones used as text
 * darkened to pass WCAG AA. Dark (explicit choice): scales inverted on the audited dark surfaces.
 * Generated values — ratios checked by the generator (see docs/specs/001-design-system-v1/plan.md).
