   COUNTDOWN v2  ·  AX HACKATHON 2026  (loaded ONLY by AX-Hackathon-Landing-v1-37)
   ----------------------------------------------------------------------------
   Research: getdesign.md → linear.app DESIGN.md
     · surface ladder carries hierarchy WITHOUT shadow
     · 1px hairline borders, ~12–14px radius (never pill, rarely 16px)
     · no skeuomorphism / no gradients / no spotlight cards
     · tabular numerals, single chromatic accent used non-decoratively
   Applied inside AX brand (canvas #000 · surface #0c0c10 · accent orange #FBB03B),
   reusing the landing's own number system (.stat orange tick + Oswald clock face).

   This file is linked AFTER styles.css, so same-specificity rules win by source
   order. It overrides the previous metallic split-flap treatment. The shared
   styles.css / scroll.js (also used by the protected v37) are left untouched.

/* ── Venue layout ─ MIRROR the JOURNEY timeline grid so the map lines up exactly
   under the "결승·결과" card (.tl-card) above it ────────────────────────────────
   .timeline = max-width 980px centered, .tl-item = grid 1fr/1fr with
   column-gap clamp(40px,6vw,90px), and .tl-card sits in grid-column 1.
   We replicate that geometry on .venue__grid (which carries the .wrap class),
   place the MAP in column 1  → identical left-x and width as the card,
   and the COUNTDOWN in column 2.                                            */
