/* ─────────────────────────────────────────────────────────────────────────
   ICON DECK — a grid of centred blocks, each an icon over a label.

   The way this product says "here are the things you can go to": the METIS
   settings page's sections, the Coherence hub, and the welcome page's "My
   events and organisations" (issue #376).

   It was not a component until that third caller. /settings/ and the Coherence
   hub each carried their own <style> block under the name .settings-*, and the
   two had already drifted: the hub's copy was missing the rules for a card
   whose icon is an image or a name's initial, so a holon logo rendered wrong
   there. Both copies also hardcoded a cream-and-gold palette that could not
   survive under another app's theme. Renamed rather than kept as .settings-*
   because it is no longer the settings page's private class.

   Markup: crm/partials/icon_deck.html (the grid) and _icon_deck_card.html
   (one card).
