/* =============================================================
   Flowency — "Waveform Studio" (light)
   A broadcast-console design language recolored to the Flowency
   purple brand. Speech is the material, so the waveform is the
   signature motif: it is the logo glyph, the section divider,
   and the live accent. Shared by every page for a consistent,
   fast, SEO-friendly experience.
