Description

A minimal pass at mobile usability: everything reachable on desktop stays reachable, nothing
overflows, and desktop layout is unchanged.

Related Issues

Relates to #666.

Changes Made

  • PageLayout — side bars become header-opened sheets below md. Below md the page's
    main region adopts focus only when it would otherwise be orphaned on <body> — the drawer's
    trigger unmounts with the old route — so a control that survives a breakpoint crossing keeps
    focus. Icon-only actions fall back to their label for the
    accessible name — below md the visible label is hidden, so it was the only one left.
  • Sidebar — fills the sheet; collapse toggle hidden.
  • Settings / Channels tab strips — one scrollable row; 16 module tabs wrapped into a block.
  • FormWrapper — field control row wraps; key fields clipped their own buttons.
  • FilterControl — popover bounded and scrollable; ran off short screens.
  • Connections — header stacks; the title was squeezed to ~145 px.
  • MessageInput — byte counter narrower below md.
  • Toaster — toast viewport clears the header while a device is connected; a long-lived
    reminder toast covered the navigation.
  • Appdvh for the connected app; 100vh overshoots the visible viewport by 56 px (measured).
  • Map — two-finger zoom below md. maplibre couples zoom and rotate in one handler, so
    rotation comes with it; upstream disables the handler outright, which also costs pinch-zoom on
    a phone. The +/ controls are unchanged for anyone who does not want the gesture.
  • Dialog — max height uses dvh; at 100vh a tall dialog put its own bottom edge below
    the fold, unreachable because it is position: fixed.

Responsive layout changes are limited to below md. The two dynamic viewport-height fixes
(App, Dialog) are width-independent by design: the bug is dynamic browser chrome, not width,
so a landscape phone or a tablet at ≥768 px needs them too. On desktop browsers vh and dvh
resolve identically. Desktop layout is unchanged.

Testing Done

  • +15 unit, +5 e2e. Suites otherwise unchanged: 400 pass / 1 pre-existing fail; e2e 8 passed /
    1 skipped, the skip unchanged from base. That one failure (transport-node-serial) is red on
    master too.
  • Pixel-diffed against a parallel build of the base at 768 and 1280: identical apart from live
    node data and nondeterministic basemap labels.
  • Manual on a phone, against a meshtasticd simulator and a physical node.

Notes for review

  • Breakpoint is the existing md (48 rem); no new breakpoint. max-md: has no precedent here —
    chosen so every rule is greppable and provably desktop-safe.
  • Tab classes repeated at 4 call sites on purpose: moving them into TabsContent would change
    AddConnectionDialog.
  • One new hook, useIsMobile; packages/ui's equivalent is not reachable from apps/web.

Maps wake to touch and gestures flow
Tests guard each mobile lane

Comment thread apps/web/src/components/PageLayout.tsx Outdated
A minimal pass at mobile usability: everything reachable on desktop stays
reachable, nothing overflows, and desktop layout is unchanged.

Relates to meshtastic#666.

- PageLayout: side bars become header-opened sheets below md. Columns don't
  fit a phone. Below md the page's main region adopts focus when it would
  otherwise be orphaned on <body>: the drawer's trigger unmounts with the old
  route, and again when the breakpoint takes the drawer away. Guarded on
  activeElement so a control that survives a breakpoint crossing keeps focus. Icon-only actions fall back to
  action.label for their accessible name before the synthetic "Action <key>";
  below md the visible label is hidden, so it was the only addressable name
  left.
- Sidebar: fills the sheet; collapse toggle hidden. Column-only affordance.
- Settings / Channels tab strips: single scrollable row. 16 module tabs
  wrapped into a block.
- FormWrapper: field control row wraps. Key fields clipped their own buttons.
- FilterControl: popover bounded and scrollable. Ran off short screens.
- Connections: header stacks. Title was squeezed to ~145px.
- MessageInput: narrower byte counter. It reserved 80px of 375.
- Toaster: toast viewport clears the header below sm, only while a device is
  connected. A long-lived reminder toast covered the mobile navigation
  entirely. UI/Toast.tsx itself is unchanged.
- App: dvh for the connected app. 100vh pushed the composer off screen.
- Map: two-finger zoom below md. maplibre couples zoom and rotate in a single
  handler and disableRotation() could not be made to run reliably on this
  stack, so rotation is enabled below md as well. Upstream disables the handler
  outright, which also costs pinch-zoom on a phone. Accepted deliberately:
  zoom is the point, and the +/- controls remain for anyone who does not want
  the gesture. touchZoomRotate={false} is retained verbatim at md and above.
- Dialog: max height uses dvh. At 100vh a dialog taller than the visible
  viewport put its own bottom edge below the fold, unreachable because it is
  position:fixed - Node Details at 390x844 is 934px of content in an 844px box.

Responsive layout changes are limited to below md. The two dynamic
viewport-height fixes (App, Dialog) are deliberately width-independent: the bug
is dynamic browser chrome, not width, so a landscape phone or a tablet at >=768px
needs them too. On desktop browsers vh and dvh resolve identically, which the
desktop A/B confirms. Desktop layout is unchanged.

Breakpoint is the existing md (48rem); no new breakpoint. Uses max-md:, which
has no precedent in this repo, chosen so every rule is greppable and provably
desktop-safe. Tab classes are repeated at 4 call sites on purpose: moving them
into TabsContent would change AddConnectionDialog. One new hook, useIsMobile;
the packages/ui equivalent is not reachable from apps/web. Touch targets on the
new mobile controls are 44x44 per the Meshtastic Client Design Standards.

No new i18n keys: reuses ui:navigation.title, ui:navigation.nodes and
common:button.close, all present in every locale.

Tests: +16 unit (11 PageLayout, 5 useIsMobile), +5 e2e
(responsive.mobile.spec.ts, 390x844). Suite otherwise unchanged: 401 pass /
1 pre-existing fail; e2e 8 passed / 1 skipped, the skip unchanged from base.

@danditomaso this is meant as an "isolated small fix" as mentioned in #971. It moves the side bars into a header drawer and makes everything reachable on a phone, using in-page scrolling where necessary — a minimally invasive usability fix, not a mobile-first redesign. All changes sit below the existing md breakpoint, desktop is pixel-identical to base, nothing preempts what might be done in future — should be easy to drop or replace it piece by piece.

Could you approve the workflow runs? A Vercel preview is the quickest way to judge it on a phone. Happy to rebase or adjust anything.
