/* ── White nail doodle wallpaper ────────────────────────────────
   Pure-CSS approach: an inline SVG data-URI pattern tiled as a
   background on a ::before pseudo-element.  Zero new HTML.
   The SVG tile (200×200) contains five hand-drawn-style shapes:
     • two almond nail silhouettes at different rotations
     • one round nail shape
     • one polish bottle outline
     • one sparkle/star doodle
   All stroked in white, no fill, so the coral gradient shines
   through.  Opacity kept at ~7% for maximum subtlety.
