   Built to the logo system and brand board.
   Logo rules observed: no glow on the mark, no recolouring, no tagline
   locked under the wordmark, clear space kept at the height of the S.
   Palette: Midnight Navy ground, Electric Cobalt primary, Soft Violet
   secondary. Sora display / Inter body. Keywords are calm and premium,
   so the page is spaced generously and the gradient stays in the mark,
   the wave, and hairline rules — never behind reading type. */
