Release 4.8.0

• Text reads at 4.5:1 in every light theme (WCAG AA; plan 2026-10-22, track H4). axe failed 50 to 155 contrast checks on every site's home in each of the 12 light themes, through three tokens:
  • --accent-light was a pale tint used as link and eyebrow text (snow's #38bdf8 on white is 2.1:1);
  • --text-muted sat at 4.1 to 4.4 on the secondary surfaces;
  • --accent sat just under the floor in a few light themes.

builtin-themes.js deriveTokens now moves a text token below 4.5:1 on any of the theme's surfaces (--bg-primary, -secondary, -tertiary, -card, -input, -hover) toward black, just far enough, measured on the rounded hex.

• Light themes: --text-secondary, --text-muted, --accent and --accent-light.
• Dark themes: the two text tokens only; their accents are the theme's brand colour and already read, so Vibe's #3b82f6 is unchanged.
• A token that already reads is left exactly as set.

theme-loader.js is regenerated. readableText, TEXT_TOKENS and SURFACES are exported. Measured on production pages with the new values applied: snow on openvibe.network went from 50 failures to 0 apart from site-specific colours, Food from 14 to 0.

• "Recently shipped" (shipped.js): the site chip's label uses --text-primary on its accent tint (the tint cost --accent-light about 0.4 of contrast).
