Closes #4

Detects mobile viewport (window.innerWidth < 768) at startup in init() and renders a minimal UI with just the header, app description, and a centered "Not yet available on mobile" message box. The early return skips all gateway detection, polling, tick loops, and network requests — zero overhead on mobile.

Changes

src/main.js

Added MOBILE_BREAKPOINT constant (768px)
Added isMobileViewport() helper
Added buildMobileUI() — renders header + description + centered message card + commit hash footer
init() checks mobile viewport first and returns early before any network activity

README.md

Added mobile detection to Features list
Added mobile limitation to Limitations section

What's NOT changed

Desktop behavior is identical — the mobile check is the first thing in init() and only fires on narrow viewports
Existing mobile-responsive CSS in styles.css is retained (applies if someone is just above the breakpoint)
No changes to Makefile, Dockerfile, linter config, or any infrastructure

Detect mobile viewport (window.innerWidth < 768) at startup and show a
centered 'Not yet available on mobile' message instead of the full
monitoring UI. All polling, gateway detection, and network requests are
skipped entirely on mobile viewports.

Desktop behavior is completely unchanged — the mobile check is the very
first thing in init() and returns early before any other setup runs.

Review: PR #8 — Mobile viewport detection

Policy Compliance

No policy violations found. Specifically checked:

Docker image references: unchanged, existing @sha256: pins intact
Makefile targets: unchanged
Prettier formatting: prettier --check . passes clean
No linter/CI/test config modifications
Feature branch targeting main via PR ✓
README sections all present ✓

Requirements Checklist (issue #4)

Requirement	Status
Detect mobile viewport (`window.innerWidth < 768`)	✅ Met — `MOBILE_BREAKPOINT = 768`, `isMobileViewport()` checks `window.innerWidth < MOBILE_BREAKPOINT`
Show friendly message instead of full monitoring UI	✅ Met — `buildMobileUI()` renders centered "Not yet available on mobile" card
Skip all checkers/polling on mobile	✅ Met — early `return` in `init()` before `detectGateway()`, `AppState`, tick loop, event listeners
Render only header + description + centered message box	✅ Met — header with title/author links, description text, centered message card, commit hash footer
No changes to desktop behavior	✅ Met — mobile check is first in `init()`, desktop code path completely untouched

Test Coverage

No new exported types or functions — all additions (MOBILE_BREAKPOINT, isMobileViewport(), buildMobileUI()) are module-private, same as every other function in src/main.js. Test coverage requirement for new exports does not apply.

Build Results

docker build . ✅ passes
make check (build + prettier) ✅ passes
Branch rebases cleanly on main ✅

Code Review Notes

buildMobileUI() follows the same HTML template pattern as the existing buildUI() — same Tailwind classes, same __COMMIT_HASH__/__COMMIT_FULL__ Vite-injected globals, same link structure
Early return prevents all network activity: zero overhead on mobile as claimed
README additions are consistent with implementation (768px breakpoint, "not yet available" language)
No security concerns — no user input in template literals
No scope creep — exactly what the issue asked for

Verdict: PASS ✅

Clean, minimal implementation that satisfies all requirements in issue #4. No policy violations. Builds clean.
