/* shepherdpsalm.org — swiss-grid-modular
   Palette: signal-red-and-cool-grey. Ornament: geometric rules.
   Site-specific stylesheet; no rule is shared with any other directory.

   FACES. Matrix row: Archivo Black (display) over Public Sans (text),
   self-hosted and subset. Font binaries are withheld from this build —
   redistribution/subsetting licences for concrete artifacts are not yet
   verified, which is a recorded pre-deployment item — so no @font-face is
   declared and the grid speaks through heavy system grotesques meanwhile.

   BADGES. This is the fleet's EN store-badge site. Official Apple and
   Google Play badge artwork is likewise a pre-deployment asset; until it
   clears, the store links render as typographic keys (.store-key), not as
   images. */
