Summary

• Keyboard shortcuts (t / arrows) fire in unintended focus contexts (dialogs open, button focus) #17 (shortcuts fire in unintended focus contexts): extracted shouldSkipShortcut() in src/shortcuts.ts. The t/arrow day navigation now skips when the shelf popover, delete-confirmation dialog, or app-settings overlay is open; skips INPUT/TEXTAREA/SELECT/contenteditable targets (also checks the contenteditable attribute, since isContentEditable is unreliable in some DOMs); and leaves ArrowLeft/ArrowRight to move focus when a BUTTON has focus.
• Consistency hazard: onMetaChange ignores meta.emoji (emoji can desync from manifest) #16 (onMetaChange ignores meta.emoji): extracted applyNotebookMeta() in src/notebookmeta.ts; onMetaChange now syncs nb.emoji from fresh backend meta (including clearing on null), so the in-memory notebook list cannot desync from the manifest after renames or re-fetches.

Verification

• pnpm test — 20 files, 93 tests passed, including new shortcuts.test.ts (popover/dialog/input/contenteditable/button-arrow cases) and notebookmeta.test.ts (emoji set/clear/preserve/unknown-id cases).
• pnpm typecheck and pnpm build pass.

Self-review pass (CodeRabbit-style) over all session changes (PRs #47, #48, and this PR):

Fixes applied in 16b24f1:

1. Shortcut guard covered too few modals (this PR's original guard only knew the app-settings overlay). Now also covers the notebook-settings dialog, the frosted prompt, and the context menu — previously t/arrows could navigate the journal behind those.
2. Image alignment regression introduced in Fix image centering regression and guard cover-title edits per notebook #48: the new default margin: 1em auto (centering) overrode explicit data-text-align=left/right because those rules set only one margin side; both sides are now set per alignment.

Verified non-issues:

• flushNow() return semantics: at boot autosave is null, so (await autosave?.flushNow()) === false is undefined === false → navigation proceeds. Correct.
• applyNotebookMeta and the shelf rename flow share the same NotebookMeta objects — no double-mutation hazard.
• createToolbar's selectionchange listener leak is pre-existing (single toolbar, never re-created) — left as-is.
• contenteditable attribute fallback in shouldSkipShortcut is needed because happy-dom (and some WebViews) don't reflect isContentEditable reliably.

Checks: pnpm test (93 passed), pnpm typecheck, pnpm build all green.
