The previous pass kept the dark base and the red icons, which did not
read as the acampada. Now:
- Light theme: white page, black ink and borders, black buttons with a
hard neon offset shadow, neon for focus and the active nav item;
h1/h2 in Anton with the stepped neon shadow of the site headings.
- Nav, empty-state, spinner and pattern assets in black; platform icons
keep their dark disc with a neon stroke.
- New mark: three dome tents wired from their doors into a switch with
an antenna, drawn in the inked style of the acampada logo (curved
poles, ball ends, hatching) over a neon offset copy. LogoMark renders
it inline; visible product name is T-HUB.
- docs/brand: t-hub.svg and a lockup with the Anton wordmark converted
to outlines so it renders without the font.
- Public submission page moved to the light palette.
Checked with headless Chromium screenshots (offline sample data) on
desktop and mobile.
