Replaces the generic shadcn/ui gray theme + horizontal top-bar shell with
the paper-and-ink language from the Claude Design handoff bundle: warm
off-white paper, near-black ink, Source Serif 4 + Inter, hairline borders,
muted ink accents (clay/indigo/sage/plum/ochre) used functionally for
calendars and share scopes.
Theme switcher expanded from 2 dimensions (theme × mode) to 7: palette ×
mode × fontPair × density × dashLayout × calView × navStyle. All exposed
in Settings → Appearance and persisted on the users row. Pre-paint script
applies all four data-* attributes from localStorage so reload doesn't
flash.
App shell restructured to a CSS-grid driven by data-nav on <html>: sidebar
on desktop, bottom-nav + FAB under 760px. Four desktop nav modes wired
(sidebar/rail/top/fab-only). Topbar gets a search-→-CommandPalette button,
notification bell, "+ New" quick-add, avatar.
Dashboard, calendar, lists, notes, settings, login, public share viewer,
and quick-add sheet all reskinned. Dashboard editor gains a Preset menu
(classic/split/glance) that fills the layout from the registered widgets.
FullCalendar wrapped in .fc-skin and inherits all paper-and-ink tokens via
CSS variable overrides. Public share viewer (/s/<token>) rebuilt around
ShareFrame: expiration banner, brand strip, eyebrow chip, 38px serif
title, mini-day + mini-map cards, share-rows.
Schema: drops users.theme; adds theme_palette, theme_font_pair,
theme_density, theme_dash_layout, theme_cal_view, theme_nav_style with
defaults that match the design (clay / serif-sans / regular / classic /
month / rail-desktop). Migration 0014_paper_ink_theme.
Middleware sets x-pathname so the AppShell server component can render
bare for /s/* and /login without a route-group refactor.
