/* =============================================================
   VEEDAY CONSULTANTS — mobile.css  (round 11: the phone layer)
   Loaded LAST on every page, after the page's own CSS. Pairs with js/mobile.js.

   "Phone" is exactly this query, everywhere (CSS and JS):
     (max-width: 700px), (hover: none) and (pointer: coarse) and (max-height: 500px)
   Every rule in this file is inside that query, except the few at the top that HIDE
   phone-only elements by default. Tablets (768+) and laptops never see any of it.

   ─────────────────────────────────────────────────────────────
   COMPONENT API FOR PAGE AGENTS (do not edit this file; use these)
   ─────────────────────────────────────────────────────────────

   VARIABLES (set on :root inside the phone query)
     --m-dock-h       height of the bottom dock bar (64px portrait, 52px landscape)
     --m-safe-b       env(safe-area-inset-bottom, 0px)
     --m-dock-space   dock height + safe area: the room the dock takes at the bottom
     --m-dock-offset  = --m-dock-space while the dock is showing, 0px while it is
                      hidden (scrolled away or keyboard open). Use it to stack a sticky
                      bar ABOVE the dock, e.g. a form step bar:
                        .my-stepbar { position: fixed; left: 0; right: 0;
                                      bottom: var(--m-dock-offset);
                                      transition: bottom .35s var(--ease); }
     html.m-dock-hidden   present while the dock is slid away
     html.m-kb-open       present while a text field has focus / the keyboard is up
     html.m-phone         present while js/mobile.js is active (phone + JS running)

   VISIBILITY HELPERS
     <div class="m-only">…</div>   hidden everywhere except phones. Shown as display:block;
                                   for another display set it inline or in your CSS:
                                   style="--m-display:flex" (or grid, inline-flex…).
     <div class="d-only">…</div>   hidden on phones only.

   RAIL  (horizontal scroll-snap row with a peek of the next card)
     <div class="m-rail" id="marketsRail" data-m-dots>   ← data-m-dots: JS adds a dots row after it
       <article>…</article> <article>…</article> …
     </div>
     or place the dots yourself:  <div class="m-dots" data-m-for="marketsRail"></div>
     Only a phone turns the container into a rail; on desktop your own layout applies.
     Card width: --m-rail-w (default 84%), gap: --m-rail-gap (default 12px).
     Children snap to the start edge, padded by var(--pad). Dots are decorative
     (aria-hidden); the active one gets .is-on. The rail gets .is-start / .is-end.

   SHEET  (bottom sheet: grab handle, drag down / tap scrim / Escape to close,
           focus trapped, page behind inert)
     <button type="button" data-m-sheet-open="contentsSheet">Contents</button>
     <div class="m-sheet" id="contentsSheet" role="dialog" aria-modal="true"
          aria-labelledby="contentsSheetTitle" hidden>
       <div class="m-sheet__panel">
         <div class="m-sheet__grab" aria-hidden="true"></div>
         <div class="m-sheet__head">
           <h2 class="m-sheet__title" id="contentsSheetTitle">Contents</h2>
           <button type="button" class="m-sheet__close" data-m-sheet-close aria-label="Close"></button>
         </div>
         <div class="m-sheet__body"> … links, text … </div>
       </div>
     </div>
     Put the sheet as a direct child of <body> (anywhere works, but body level is cleanest).
     Links inside a sheet close it when tapped (same-page #hash links scroll after closing).
     Events on the sheet element: 'm-sheet:open', 'm-sheet:close'.

   TOAST
     window.vdMobile.toast('Address copied');           // 2.4s, role=status, above the dock
     window.vdMobile.toast('Saved', { duration: 1600 });
     (No-op off phones. Created on demand; you add no markup.)

   JS API  (window.vdMobile, defined as soon as js/mobile.js runs; methods are
            safe no-ops off phones)
     vdMobile.PHONE              the media query string above
     vdMobile.isPhone()          true while the phone layer is active
     vdMobile.toast(text, opts)
     vdMobile.openSheet(id, openerEl?) / vdMobile.closeSheet()
     vdMobile.haptic()           8ms tick on Android; nothing under reduced motion
     vdMobile.refreshRails()     re-scan .m-rail after you add one dynamically
     vdMobile.dock               the <nav class="m-dock"> element
     document 'vd:phone' event   detail: { active: true|false } when the layer turns on/off
     Wait for it with:
       window.vdMobile ? go() : document.addEventListener('vd:mobile-ready', go, { once: true });
     and check vdMobile.isPhone() / listen to 'vd:phone' to set up and tear down your own phone bits.

   PRESS FEEDBACK
     .btn, .m-press and [data-m-press] scale to .97 while pressed; dock items dim.
     Add class="m-press" to any tappable card of your own (not to [data-reveal]
     elements whose transform is animated; put it on an inner element instead).
