   birthday-teen-glow-flyer-neon-surge — styles.css
   "Neon Surge" — a neon glow-poster flyer for a teen birthday party.

   Palette (deep-space violet-black + hot neon):
     space    #07030F · #0D0720 · panel #120A26 · raised #1A0F33
     neon pink #FF2E88 · neon cyan #2BE4FF · neon purple #A45CFF
     neon lime #C6FF3D · neon yellow #FFE14D
     ink #F3EFFF (near-white) · muted lavender #A99BCB

   Layout: one 100dvh shell — masthead / tabs / active panel / foot.
   Only the active panel scrolls (html.js gates this; without JS the page
   reads as a normal scrolling document).

/* ── optional Free Page — repeatable host-written blocks ──────────────
     Each .free-block is one row of the Free Page group: a free title,
     free text and an OPTIONAL photo. The engine clones the blocks from
     the host's entries and removes .free-media when a row has no image,
     so a block always reads cleanly as title + text. Tapping the photo
     opens it in the lightbox with zoom, like every other photo slot. */
