/* ── gumroad overlay, de-branded ──────────────────────────────
   Adding .gumroad-button is what binds the checkout overlay, and it drags
   Gumroad's entire button skin along with it: black background, hot pink on
   hover, 4px radius, their own font, no shadow, different padding and leading.
   It also appends <span class="logo-full"> and paints a GUMROAD wordmark into
   it, so the button reads "Buy for $9 GUMROAD".

   Every property below is one their stylesheet actually sets — measured, not
   guessed. !important throughout because their CSS is injected at runtime and
   always lands after this file: source order cannot win here, only specificity
   plus weight. It also arrives async, so without this the button renders
   correctly for a beat and then turns pink.

   If a Gumroad update changes the skin, the tell is the buy button drifting
   from .btn-primary — compare the two CTAs against "View the source". */

     their pink, as bare channels for rgb(var(--accent)). Same variable name
     this site uses. Every declaration here referencing var(--accent) therefore
     received three numbers, became invalid at computed-value time, and dropped
     to transparent with no shadow — which is why background could not be
     overridden by weight alone. `inherit` takes the value from the parent,
     where it is still this site's accent, and keeps the theme switch working. */
