/* Valencia OPS / Bridge Power: shared design tokens + base styles.
   Direction: deep maritime neutrals (ink navy, blue-biased slate) with one electric cyan accent.
   Light and dark are designed separately; dark follows prefers-color-scheme unless data-theme overrides.
   Series colours are fixed by entity (dataviz reference palette); do not reorder. */
