/* =============================================================================
   PHOTOLOG DOWNLOADS — hover button, strip button, dialogs
   =============================================================================
   Loaded by BOTH public shells when the project offers downloads, next to
   photolog_group.css and for the same reason: Journal loads neither
   project.css nor Bootstrap, so anything downloads need lives here.

   Everything is deliberately layout-agnostic. These elements appear over
   three very different page designs (simple, essay-01, journal) and must
   read as chrome that belongs to the photograph, not to any one layout:
   near-black circles on the image (the lightbox's visual family), and plain
   neutral dialogs.
   ========================================================================== */

/* --- the per-image hover button ------------------------------------------
   Injected by photolog_download.js into each image's parent, which gets
   .pf-dl-host. Port of lrgallery's .lrgc-dl-btn recipe: quiet until the
   photograph is approached, revealed on hover AND :focus-within (keyboard),
   always visible where hover does not exist (touch). */
:root {
  /* The editor's motion curve (--pfe-ease in editor_form.css), restated

     deceleration curve across the product, whichever side of the login. */

   Native <dialog>: the platform provides the top layer, the backdrop, the

   sit over all three layouts without borrowing any one's voice. */

   A collage tile is a fraction of a row wide at EVERY viewport, so this is a

   by a container query.

   ⚠ This was `container-type: inline-size` on .pf-dl-host until 2026-08-25,
   and it broke the Journal layout in production: size containment makes an
   element's inline size resolve WITHOUT its contents, and .pf-essay__media
   then collapsed to an intrinsic default (1280px photos rendered at 768, some
   at 320). Carousel slides and the Essay preset were unaffected, which is
   exactly why a narrow test missed it. Never put containment on a host whose
   width the layout derives from what is inside it. */
