Phase 01 Plan 04: Device CRUD UI and CSS Variable Fix Summary

Gap-closure plan: added device add/remove form to DEVICES panel and fixed CSS variable naming — closes DEV-03 (device list with UI interaction) and UI-02 (CSS contract alignment)

Performance

• Duration: ~2 min
• Started: 2026-04-05T20:11:51Z
• Completed: 2026-04-05T20:13:30Z
• Tasks: 2 (both auto)
• Files modified: 3 (index.html, app.js, style.css)

Accomplishments

Task 1: Device CRUD UI

• Added <form id="add-device-form" class="device-form"> to the DEVICES panel in index.html, with inputs for name (text), strip_type (select: sk6812/ws2801/generic), led_count (number), ip (text), port (number, default 21324), and a submit button "+ ADD DEVICE"
• Added apiPost(path, data) and apiDelete(path) async fetch helpers to app.js (positioned after WS_URL const, before LightSyncClient)
• Updated loadDevices() device row template to include a .device-remove button with onclick="removeDevice(d.id)" alongside a .device-row-info wrapper for the name/metadata
• Added removeDevice(id) function that calls apiDelete(/api/devices/{id}) then refreshes the list; exported as window.removeDevice for ES module compatibility with inline onclick handlers
• Added form submit handler that calls apiPost("/api/devices", data), resets form (restoring port default to 21324), then refreshes the device list
• Added panel IDs to all four panels: id="devices-panel", id="animations-panel", id="timeline-panel", id="transport-panel"

Task 2: CSS Variable Naming Fix

• Added --accent: #00ffff as canonical variable in :root
• Changed --border-bright and --text-accent to be aliases: var(--accent) instead of hardcoded #00ffff
• Added .device-form CSS rule: flex-column, 4px gap, border-top separator from device list
• Added .device-remove rule: borderless button, dim text, hover turns red (#ff3333)
• Updated .device-row to display: flex; align-items: center; justify-content: space-between to accommodate remove button alongside info
• Added .device-row-info flex-column wrapper for name + metadata within each row

Task Commits

1. Task 1: Device CRUD UI — ccc40c8 (feat)
2. Task 2: CSS variable fix + device form styles — 2ff35f9 (feat)

Files Created/Modified

• lightsync/frontend/index.html — added form, panel IDs, timeline/transport panel wrappers
• lightsync/frontend/app.js — added apiPost, apiDelete, removeDevice, form submit handler, updated device row template
• lightsync/frontend/style.css — added --accent canonical variable, aliases, device form and remove button styles

Decisions Made

• Panel IDs added in Task 1: The HTML file was already being modified for the form, so panel IDs were added in the same edit pass to minimize diff noise. Task 2 only touched CSS.
• window.removeDevice export: ES modules scope all declarations — onclick="removeDevice(...)" in dynamically rendered HTML requires the function to be on the global window object.
• No refactor of --text-accent usage sites: --border-bright and --text-accent are now aliases of --accent. No existing CSS rules using these variables needed to change — the alias pattern lets the semantics remain meaningful (text-accent vs border-bright) while sharing a single source color value.

Deviations from Plan

None — plan executed exactly as written. Panel IDs were added in Task 1 edit rather than Task 2 (minor sequencing optimization, not a behavioral change).

Requirements Closed

Requirement	Status	Evidence
DEV-03	CLOSED	Add-device form in DEVICES panel; POST/DELETE wired; device rows have remove buttons
UI-02	CLOSED	--accent: #00ffff canonical variable present; --text-accent and --border-bright are aliases; all four panel IDs present

Verification Results

1. grep "add-device-form" lightsync/frontend/index.html — MATCH
2. grep "apiPost\|apiDelete\|removeDevice" lightsync/frontend/app.js — 4 matches (function defs + window export + apiPost call in form handler)
3. grep "\-\-accent.*#00ffff" lightsync/frontend/style.css — MATCH
4. grep "devices-panel\|animations-panel\|timeline-panel\|transport-panel" lightsync/frontend/index.html — 4 matches

Known Stubs

None — all gap-closure work is fully wired. The form submits to a live API endpoint. Device removal calls a live DELETE endpoint.
