/* ======================================================================================================
 * Version: 1.16.0
 * Created: 2026-06-11 SAST
 * Updated: 2026-06-13
 * File: eco-guilds-guild-album.css
 * Path: assets/css/eco-guilds/partials/eco-guilds-guild-album.css
 * Author: Buktika - Binka
 * Purpose: Block 1 (BKT 40050) — the shared "family album" pane: a floating card opened on
 *          guild-pin hover, anchored BESIDE the pin (JS-positioned). Layout: 2x2 family tiles
 *          on top, a 1x2 "storybook" (media stage | story prose) at the bottom.
 * License: © Buktika, 2026. All rights reserved.
 * Governance:
 *   - BKT-PIL-02 Eco Guilds + Colour Map Whitepaper v3.14.0.
 *   - Selectors scoped under .page-eco-guilds-farms (Colour Map §9). Tokens only — no hex
 *     literals for token-representable values (§2.3). rem for spacing/type (§15); border/shadow px ok.
 *   - Media expansion uses the canonical Media Lightbox (§8.8); this file styles thumbnails only.
 * ChangeLog:
 *   v1.16.0 (2026-06-13): Made tappable tiles read as real buttons (owner: "feeble arrow; Farmer
 *     Hannes won't know it's a button"). .is-link now has a RESTING pillar-accent border + glow
 *     (per-pillar --tile-glow), LIFTS on hover (translateY -3px + stronger glow, matching the
 *     design-system button motion) and presses on :active; the grey arrow became a round white-on-
 *     accent "go" badge. Touch (@media hover:none) gets a bigger badge + stronger resting glow,
 *     since hover-lift is unavailable there. Reduced-motion respected.
 *   v1.15.0 (2026-06-13): Replaced the oversized explore button with the Apple tappable-card
 *     pattern — .eg-album__tile.is-link (whole card tappable) + a quiet .eg-album__chev disclosure
 *     chevron (systemGray) top-right. No proportion change. Removed .is-explore / __explore-hint.
 *   v1.14.0 (2026-06-13): The Eco Guild tile is now a button into the farms — .is-explore makes it
 *     read as tappable and .eg-album__explore-hint shows a touch-only "Tap to view the farms ▸"
 *     call-to-action inside it. Pairs with album JS v1.8.0 / map JS v2.15.0.
 *   v1.13.0 (2026-06-13): Touch foundation. Backdrop now a dimmed scrim. Added .eg-album__closebar
 *     — an oversized (~64px), full-width, high-contrast, sticky close bar shown only on touch
 *     (@media hover:none), replacing the small corner × there; sized per elderly-target research.
 *     Mobile sheet max-height 74->80vh. Desktop unaffected. Pairs with album JS v1.7.0.
 *   v1.12.0 (2026-06-13): Added .eg-album-backdrop — transparent full-screen tap catcher (z 1499,
 *     just below the album) for the mobile "tap map to close" behaviour. Shown by JS on touch
 *     devices only; desktop hover is unaffected. Pairs with album JS v1.6.0.
 *   v1.6.0 (2026-06-12): Pillar-colour correction + wider/shorter. Reporters tile accent fixed
 *     to its canonical primary mama-amber #f5b014 (was reporters-orange, which is only the
 *     accent — and read as a near-duplicate of MamaDEX terracotta). Pane widened 34->40rem and
 *     vertical rhythm tightened so it reads shorter (owner: "wider, not taller").
 *   v1.5.0 (2026-06-12): Viridians-grade polish (owner: keep solid, no glass). Per-pillar colour
 *     differentiation on the four tiles — a left colour segment + faint tint per pillar (Eco
 *     green-deep, MamaDEX mama-earth, EduTower edutower-blue, Reporters reporters-orange), the
 *     same colour-segment language as the Viridians map popup. Headings switched to the system
 *     sans stack (Apple-native). Close control rebuilt as a circular two-stroke control. Subtle
 *     scale+fade open animation (reduced-motion aware). Per-pillar background tints are permitted
 *     rgba() tints of each canonical pillar primitive (Colour Map §8.9.4 tint exception).
 *   v1.4.0 (2026-06-12): Wider story card (30->34rem) + Apple HIG-leaning surface: 1.25rem
 *     corner radius, layered contact+ambient shadow, momentum scroll. NOTE: frosted-glass
 *     (backdrop-filter) is intentionally NOT used — Colour Map §8.2 reserves glass exclusively
 *     for .btn-hero-secondary. Pending owner decision on overriding that for this panel.
 *   v1.3.0 (2026-06-12): Pin-anchored + substantial. Pane is JS-positioned beside the pin (not
 *     glued to the viewport edge). Titlebar is now a STICKY solid header with a divider + amber
 *     accent rule, so it can never overlap the tiles. Type scaled up across the card. Body moved
 *     into a padded .eg-album__body wrapper (pane itself owns no padding so the sticky header
 *     spans full width).
 *   v1.2.0 (2026-06-12): On-spec tokens + 2x2 tiles / 1x2 storybook + slideshow.
 *   v1.1.0 / v1.0.0: earlier iterations (superseded).
