/* ==========================================================================
   StockSmartPro — phone ergonomics layer
   Loaded after app.css. Every layout rule here is scoped to narrow viewports,
   so tablet/desktop rendering is unchanged. Brand tokens come from app.css.

   Rules of this layer:
   - interactive controls are at least 44x44 CSS px (glove/hurry use in a kitchen)
   - form controls are 16px so iOS Safari does not zoom on focus
   - nothing may widen the viewport: no horizontal page scroll at 320px
   - fixed bottom tabs respect env(safe-area-inset-*) on notched phones
   ========================================================================== */

/* ---------------------------------------------- collapsible form sections */
/* Markup: <details class="disclose" data-fold open><summary>…</summary><div>…</div></details>
   Desktop hides the summary chrome so the page looks exactly as before; the
   phone layer closes data-fold sections on load (see templates) and shows the
   summary as a 48px tap row. */
