Two regressions from the cleanup cycle, caught in E2E:
1. The unexport pass stripped loadTheme, loadUserTheme, and
updateThemeIndicators from the Alpine.data("theme") registration —
the member-removal pass could not tell export-block lines from
Alpine component object lines. Theme dropdowns on docs and
non-app pages stopped reflecting the active theme. Members
restored (functions were kept, only their scope registration was
lost).
2. The new Content-Security-Policy shipped script-src without
'unsafe-eval'. Alpine evaluates every @click / x-init / x-show
expression through new Function(), so the CSP silently disabled
ALL Alpine interactivity app-wide: sidebar categories stuck open,
modals rendering unhidden and unresponsive, dropdowns inert.
script-src now includes 'unsafe-eval' with a comment explaining
the Alpine requirement.
