/* ── 2. THE LIST: an on-fire project's name in ONGOING PROJECTS ──
   The outline (#2A0709) is extruded like 3D lettering (2026-10-27, per Pranesh, matching his
   #1000Masteries / LEGENDARY references): a 1px hairline all round, then stacked hard
   drop-shadows stepping down-right, so the top/left edge stays thin (~1px) and the
   right (~3px) and bottom (~5px) read as the letters' dark sides. Earlier: an even 2px
   ring + a #5C343B offset shade; a lighter warm-grey ring was tried and reverted. Drop-shadows, not text-stroke:
   a stroke paints over a background-clipped fill. The glow sits on top. */
