/**
 * Variant CSS: process--tabs-by-phase
 *
 * A static phase-tab strip (one tab .is-active) above a framed panel that shows
 * the active phase's steps (numbered chip + title + desc in a row). Groups the
 * process into named phases rather than one long sequence — distinct from the
 * timeline, row, node-line, card, ghost and cycle variants. Tabs are real,
 * editable paragraphs styled as pills; the active pill takes the accent.
 * Polarity-aware text (--ink). Part of the `process` role. Scoped to the variant.
