   THE CAVE — cave.css (Cave-002 Threshold build)
   ------------------------------------------------------------
   Reconstructed from the approved Cave-002 screenshot since the
   original v0.5.1 working files were lost. Positions and the
   display font are matched by eye against that screenshot, not
   measured from source — nudge freely if anything sits off.

   v0.5.2 — replaced placeholder .journey-guide circle with a
   built (CSS/SVG, no raster asset) leather-pocket Wayfinder:
   coin peeks from the opening, flap + snap sit in front, coin
   carries the slow "heartbeat" glow per the Wayfinder concept.

   v0.5.3 — balance pass: pocket enlarged + given an ambient
   halo so it reads clearly against the backdrop; removed the
   now-redundant "YOUR WAYFINDER AWAITS" label; mid-block
   re-centered in the open band between title and nav via
   top/bottom + flex instead of a fixed top%; added a soft
   radial scrim behind mid-block for legibility.

   v0.5.4 — fixed the v0.5.3 scrim (it was sized to the tall
   positioning band, not the actual text, so it did nothing
   useful): now wraps a snug .mid-inner content box instead.
   Gave the pocket a gold trim/rim-glow so it reads against
   the dark corner of the art. Added the Wayfinder arrival
   ritual: a representative coin graphic travels from the
   doorway into the pocket once per visitor (localStorage-
   gated, reduced-motion aware) — separate from the eventual
   functional nav medallion, which will live in the pocket.

   v0.5.5 — REGRESSION FIX: v0.5.4's mid-block re-centering
   pushed the text into the brightest part of the waterfall,
   and the plaque backgrounds turned it into a muddy block.
   Reverted to a fixed, vertically-centered position matching
   the approved Cave-002 reference; dropped the plaques for
   clean layered text-shadow only (mid-final now cream/white
   like the title, matching the reference). Added the "Every
   explorer has a Wayfinder. This one is yours." caption,
   fading in only while the coin holds still mid-flight. Gave
   both coins eight compass tick marks (echoes the eight-
   destination-segment design). Made the Wayfinder pocket
   functional: clicking it now steps through the three preview
   destinations (Hall of Echoes → Sanctuary Basin → Ancient
   Door) — scoped first pass, not the full eight-path site nav.
