+ *
+ * Anchored to the wheel: a hue-tinted `wellness-tile` surface keyed to the
+ * ACTIVE phase (`--tile-hue`), so it reads as part of the ring, not a generic
+ * tip card. Three zones:
+ *   1. phase name + hue dot,
+ *   2. a short, factual, descriptive-only "what's happening" line (curated i18n,
+ *      never clinical advice / a medical claim),
+ *   3. a "you often notice this here" chip row sourced from the user's OWN
+ *      symptom-by-phase history (`symptomPatterns`), filtered to symptoms that
+ *      cluster in THIS phase — never a generic population claim — plus a
+ *      "log today" nudge into the existing day-log sheet.
+ *
+ * Honesty gate (Clue precedent): when prediction is disabled / raw-chart mode
+ * or fewer than three observed cycles, the predictive framing is suppressed and
+ * the card shows a calm "still learning" line instead of phase copy + chips.
+ *
+ * Motion: NO competing animation. The card rides the wheel's once-per-session
+ * reveal — `animate` drives the shared `wellness-tile-rise` keyframe (a single
+ * calm entrance), which the global `prefers-reduced-motion` block already
+ * zeroes. No bespoke transitions.
