/**
 * Colour sources for conditional formatting rules.
 *
 * A rule paints one CSS value (`ConditionalRule.bgColor`), and this module is
 * where that value comes from:
 *
 *   palette → `RULE_COLORS`, translucent tints over the row background
 *   status  → `--status-badge-*-fill`, the exact fills the status chips use, so
 *             "highlight the overdue rows" and the Overdue badge agree. The
 *             tokens are redefined per theme and per high-contrast mode, so the
 *             fill flips with the surface instead of stranding light ink on a
 *             light fill.
 *   custom  → the user's colour, wrapped at the palette's tint strength. Tinting
 *             rather than filling is what keeps body text above the contrast
 *             floor in both themes without pairing an ink per rule (P8).
