/* ========== ZoomDiff Hero Publication Links: Code · Coming Soon Button (non-clickable) ========== */

/* Parent button: reuses Bulma .button / .is-normal / .is-rounded, only tweaks to hint "disabled".
   Kept intentionally close to the arXiv .is-dark button in height/padding so the two align.

   VISUAL FIX (2026-09-23):
   - Previoulsy had opacity:0.88 AND Bulma default .button[disabled] enforces opacity:0.5,
     making the button near-invisible on default state.
   - Now we use a light-grey background + dark-grey text/icon to act as a CLEARLY-VISIBLE
     secondary button (vs arXiv's dark primary). We EXPLICITLY set opacity:1 on :disabled
     to override Bulma's built-in fadeout. The disabled-ness is conveyed via cursor +
     tooltip + not-allowed cursor + green "Coming Soon" badge, NOT via fading the button.
