   PROOFFLUX — store.css
   ----------------------------------------------------------------------------
   ADDITIVE ONLY. Loaded after main.css and only by digital-products.html
   and the product pages (<slug>.html).
   It defines nothing that main.css already provides and overrides nothing,
   so it cannot affect any existing page.

   Every value below comes from the tokens declared in main.css :root — no new
   colours, no new fonts, no new radii.
   ========================================================================== */

/* --- Hiding ---------------------------------------------------------------
   The browser's own rule for the hidden attribute is display:none, but any
   author rule that sets display beats it — and main.css sets .card{display:flex}
   and .grid{display:grid}. Without this, toggling `hidden` on the grid or the
   empty state does nothing and BOTH end up on screen at once.
   Scoped to the store's own elements so nothing else is affected. */
