mangavalkandClaude Opus 5.5 b347f1c63f Import ESP_UniClock (upstream 1189810) 
Vendored from https://github.com/gpeter62/ESP_UniClock: the sketch
source, the web UI and the libraries the ESP8266 build needs, unpacked
from the bundled zips. Adds a PlatformIO project for the ESP-12. The
source is unchanged; local changes follow as separate commits.

// NeoPixel Word Clock
//
// ============================================================================
// This driver is fundamentally different from the other (tube/VFD/Numitron/
// LED segment) drivers in this codebase: instead of multiplexing digit tubes,
// it lights up individual letters/words on a WS2812 ("NeoPixel") LED matrix
// mounted behind a laser-cut/printed acrylic panel, so the time is spelled
// out as a sentence (e.g. "IT IS HALF PAST TEN") rather than shown as digits.
//
// Hardware: an XMAX x YMAX (currently 11x11, see clocks.h) grid of WS2812
// LEDs wired in a single serpentine ("boustrophedon") strip, plus a handful
// of extra individually-addressed LEDs (weekday row, minute dots, wifi/temp
// indicator) appended after the grid. Driven via NeoPixelBrightnessBus.
// A 5x7 pixel font (font5x7.h) is reused from the tube drivers to render
// small numeric overlays (temperature/humidity/date-time editor) on top of
// the same matrix.
//
// Language variants: the actual word layout (the `matrix[][]` character grid
// used to look up each word's on-screen position) and the HH:MM -> sentence
// templates (`sequence[][]`) are NOT in this file -- they live in clocks.h,
// one block per clock model:
// CLOCK_80 = English ("it is quarter past ten")
// CLOCK_81 = German ("es ist viertel nach zehn" style, uses "vor/nach halb")
// CLOCK_82 = Hungarian ("negyed tiz" / "harom negyed tiz" style)
// All three define WORDCLOCK and share this single .ino as their driver;
// only the word/sequence/matrix tables (and START_CORNER wiring direction)
// differ per config. Hungarian time phrasing is grammatically irregular
// (quarters count towards the NEXT hour, e.g. "negyed" = quarter of the
// hour to come, "haromnegyed" = three-quarters/quarter-to) -- see showTime()
// below for how the generic #1/#2 token mechanism copes with that.
//
// Note: wordclock_hun.txt in the repo root is NOT read by this code at
// runtime -- it is a captured serial debug log (DPRINT output) from a past
// firmware build, kept only as human-readable reference documentation of
// the Hungarian matrix/sequence layout, not a data file this .ino loads.
