     --card-bg bumped from --neutral-700 (0.04) to a custom 0.06 same day —
     cards were losing their edges against the page bg. The neutral ramp
     stays untouched so other surfaces using --neutral-700 are unaffected.
     --text dropped from --neutral-50 (0.98) to a custom 0.92 same day —
     pure-white text at heavy weight on a near-black bg produces halation
     (the white characters bloom outward and the eye cannot focus a sharp
     edge). 0.92 is still well above accessibility contrast minimums and
     dramatically reduces eye fatigue during long reading. */
