/* "Aifu" wordmark inline within body copy — wrapped by JS.
   Three contextual treatments because Fredoka's higher x-height and
   rounded forms read differently inside body / title / button:

   - Default (body paragraphs, Manrope 400 @ ~1rem):
       weight 500, size 0.95em → integrates with the lighter body
       weight; Fredoka stops looking "bold" inline.

   - In display titles (Fraunces 400, large display):
       weight 500, size 0.92em → compensates Fredoka's chunkier
       silhouette next to elegant serif glyphs; brand still pops
       because of size + color, not by being heavier than the title.

   - In buttons (Manrope 600 @ ~0.94rem, dense layout):
       weight 600, size 1em → matches button bold weight and avoids
       the brand mark looking "weak" inside the CTA.

   Real lighter weights are served from the Google Fonts variable
   declaration in the top @import; the local SemiBold @font-face
   remains for the wordmark surfaces (logo, closing wordmark). */
