/**
* The LYT programme — activities and the rewards they pay out in.
*
* Ordered by urgency rather than by data type: what's expiring, then the
* headline numbers, then what customers can DO to earn, then the catalogue of
* what they spend on, then the analysis. A merchant opening this page is
* usually here because something needs extending or pausing.
*
* 1 LYT = ₹1, so "outstanding" figures are simultaneously a count and a
* rupee liability — which is why they lead.
*
* ── The activity half ─────────────────────────────────────────────────────
* Activities sit here, above rewards, because they are the earning side of
* the same ledger: an activity issues LYTs, a reward spends them, and a
* merchant tuning the programme is trading one against the other. The
* dashboard shows six activities as a summary of engagement; this page is
* where all ten are managed, and it reads the SAME activity model — see
* ActivityProgramme.
