flanner 0.7.1

Added

• Brand favicon (inline SVG, three-rule document mark) and theme-color meta for
  the light and dark palettes, so the browser chrome matches the page.
• Craft details: selection uses the accent wash, scrollbars are theme-aware,
  numeric data (counts, versions, dates) uses tabular figures, and a print
  stylesheet renders a plan as a clean document (drops the app chrome).
• Keyboard-shortcuts help sheet: press ? (outside a text field) for a native
  dialog listing the shortcuts.
• Snappier navigation: internal links are prefetched on hover, and supporting
  browsers get a smooth cross-page transition (disabled under reduced motion).
• Inline duplicate-name check on the new-project and new-plan forms: typing a
  name that is already taken warns immediately (reusing the search index)
  instead of waiting for the server to reject the submit.
• Filter and sort on the projects list and a project's plan list: a search box
  narrows the visible rows and a sort control orders by name, created, or last
  updated. Client-side over the loaded page (global search is the palette).
• Command palette (Ctrl/Cmd+K, or the nav "Search" button): a native <dialog>
  that fuzzy-filters every project and plan and jumps to it. Arrow keys move the
  selection, Enter opens, Esc closes; the index is served by a new /api/search
  endpoint. Focus trap, Esc, and backdrop dismissal come from the native dialog,
  so it adds no library.
• Web UI design tokens: a 4px-based spacing scale, three elevation tiers, and
  motion tokens, so spacing and shadows are systematic rather than ad hoc.
• A real toast component for client-side notifications (bottom-right, aria-live,
  per-status left accent bar, dismiss button, reduced-motion aware), replacing
  the previously unstyled notification and built entirely on the tokens.

Changed

• Static assets are now stamped version-<mtime> (newest file under static/)
  so an edit-and-restart busts the browser cache even within a release;
  previously the tag was the version alone, so mid-release CSS/JS edits could be
  served stale.
• The dashboard's third stat is now "Updated this week" (plans touched in the
  last 7 days), a real signal, instead of the length of the recent-activity list
  (which was capped at 10 and so plateaued as a vanity number).

Security

• Rendered plan markdown is sanitized (nh3) before being inserted with |safe,
  stripping <script>, event handlers, and javascript: URLs while keeping the
  formatting and code-highlight markup. Adds the nh3 dependency.

Fixed

• Web UI review pass:
  • Mobile: the projects grid no longer forces horizontal page scroll (its
    minmax minimum exceeded the viewport), and rendered markdown tables scroll
    within their own box instead of the page.
  • Short form fields (version notes, descriptions) no longer stretch to 320px;
    only the main content editor is tall.
  • Reading presets (Book/Night) now style code, tables, and quotes consistently
    regardless of the OS light/dark theme (they set a full local palette).
  • Dark mode: the "Disabled" badge and the reading-settings popover shadow are
    theme-aware instead of hardcoded light values.
  • Consistency: info/version grids lay out in even columns; card padding is
    uniform; the first markdown heading no longer gets a stray top gap; the
    history file-path is a plain code span, not a dead link.
  • A11y: reading-settings groups are role="group" and labelled, and the
    version selector has a real <label>. The reading popover now closes on Esc
    (returning focus to its button) and its segmented controls move with the
    arrow keys.
  • No layout shift when the plan editor upgrades: the plain textarea reserves
    the same height (60vh) as the CodeMirror that mounts over it.
  • Mobile: dashboard stats stack (no orphaned third card) and small action
    buttons get a 44px touch target.
  • Cosmetic/cleanup: empty project dates show - consistently; the recent-
    activity stat is relabelled; dead .form-card and duplicate form-input CSS
    removed.
  • Plan editor: the Version Information card was nested inside the form card
    with its top border flush against the Save button; it is now a separate
    section below the form, so the button no longer looks joined to it.
