/* =====================================================================
   PRIVATE / PREMIUM CONTENT LAYER — added 2026-07-31
   Additive only. No existing rule above was deleted or repurposed.
   The shared :focus-visible ring, the .sr-only helper and the svg.ico
   sprite sizing all live in css/style.css, which every tour page also
   loads — they are not repeated here.
   ===================================================================== */

/* ---------------------------------------------------------------------
   GALLERY THUMBNAILS — <div> becomes <a href>  (bug #5)
   80 thumbnails across the 8 tour pages opened the lightbox on mouse
   click only. They now ship as real anchors —
   `<a class="gallery-item" href="{image}" aria-label="ขยายภาพ…">` in all
   eight static pages and in js/tour-detail.js — so they are focusable,
   have an accessible name, and fire on Enter, which js/lightbox.js
   intercepts with preventDefault.

   This block used to be scoped `button.gallery-item` (findings #31/#36/
   #41): the CSS author wrote for a <button> conversion, the markup
   author shipped <a>, and the selector matched zero elements in the
   repo. Nothing broke visually — .gallery-grid blockifies the anchors so
   aspect-ratio and background-size still apply — but the
   background-color placeholder never painted while a thumbnail loaded.
   Retargeted to a.gallery-item; button.gallery-item is kept alongside so
   the resets survive a future revert to <button>. The UA-reset
   declarations (padding/border/font/appearance) are harmless on an
   anchor. .gallery-item keeps its own background-image (set inline per
   tile), so only background-color is reset here.

   only thing distinguishing it — the shared two-tone ring in style.css
   already handles that. This just guarantees the ring is not clipped by

   PDF BUTTON — only rendered where a file exists (bug #6)
   js/tour-detail.js gates the button on a data flag. When no brochure
   exists the LINE consultation CTA takes the slot; nothing here needs to
   hide anything, but the rule below keeps a gated-off button from ever
   being revealed by a stale cache of the old markup.
