/* ============================================================
   ACE² Lab — Members page
   Editorial Academic Minimalism · loaded on /members/ only

   Principles
   1. Editorial calm     — hairlines and whitespace, not boxes and shadows
   2. Dual-script pairing — one family (Pretendard) for Hangul + Latin
   3. Tone over chroma    — slate neutrals; one muted navy accent
   4. 4px rhythm          — every space and line-height is a multiple of 4
   5. Parity              — Co-PI cards are twins; roles are typographic
   ============================================================ */
