Summary

• The previous in-app browser fix (252da93) caught errors from storage method calls (setItem/getItem), but X's in-app browser blocks the property access itself — window.localStorage throws SecurityError before safeStorage() even runs
• safeStorage() now takes a type string ('local'/'session') and accesses the storage property inside its own try/catch
• Also wraps the inline theme script's localStorage call in try/catch

Root cause

// BEFORE: localStorage evaluates as an argument → throws → module crashes
let authStorage = safeStorage(localStorage);

// AFTER: property access is inside the try/catch
let authStorage = safeStorage('local');

When the module crashes, main.jsx can't import it, createRoot().render() never runs → blank page.

Test plan

• Reproduced blank page with Playwright by blocking window.localStorage property access
• Verified fix: page renders fully (title, subtitle, author, body) with storage blocked
• Build passes
• Test on staging: open a published essay link in X's in-app browser
