v0.7.0

Guideline-flavored Tetris clone built with Rust + Bevy.

How to run: download the archive for your platform, extract it,
and run the bevytris binary. Keep the bundled assets/ folder
next to the executable.

• Solo modes: Marathon, Sprint (40-line race, with a personal best) and ZEN —
  endless and unlosable, where gravity never rises, topping out just wipes the
  field, and every line ever cleared feeds a lifetime ZEN level
• Two 30-stage VS CPU campaigns (first-to-n rounds, S-D grades): the classic ladder
  and ZONE BATTLE, whose time-stop super move charges by cancelling garbage
• CUSTOM MATCH: pick the opponent (CPU or a second player on the same keyboard),
  CPU level & style, first-to-N, zone, margin time, gravity, hold on/off,
  preview count, garbage messiness, attack handicaps and starting garbage
• Local two-player on one keyboard, with its own key set for player 2 (or the
  second gamepad) — every custom rule applies to both boards
• Six characters — MINT, ROSA, AMBER, VIO, COBALT and ASH. Each stands behind
  their own board, calls the line count out loud, cuts in on a tetris, a
  T-spin, a perfect clear or a garbage cancel, and has a pose for winning and
  one for losing. Original designs; the voices are synthesized with VOICEVOX
  and each pack credits the voice it borrowed, on screen in the picker
• Drop a folder into assets/characters/ to add your own — art and voice
  files, no code. See assets/characters/README.md
• CPU opponents plan like MisaMino / Cold Clear: beam search with soft-drop tucks,
  SRS spins and self-built T-spin doubles at higher stages
• SRS, 7-bag, hold, T-spins, B2B, combos, guideline scoring, margin time
• Everything is rebindable, menu controls included, and one action can answer
  to several inputs — put hold on both shoulder buttons if that suits your
  hands. Right on a binding row adds an input, left removes one
• Gamepad support, DAS/ARR/SDF tuning, VSync & fullscreen (F11)
• English / Japanese UI, auto-detected from the OS (switchable in settings)
• HDR bloom, particles, shockwaves, board inertia, Misaki pixel font
• Chord blocks: the melody rests and all three pulse channels hold one
  voicing between them, held or strummed string-by-string. Solo and zen
  build their pieces around these; versus visits them twice
• Seven melody instruments — pluck, soft, sustain, piano, guitar, marimba,
  brass — one rolled per piece, so two pieces on a preset do not arrive
  with the same voice on the tune
• No music files. A nine-voice NES-style synthesizer and an algorithmic
  composer write the BGM live: bright and unhurried in solo, fast and minor
  in versus, with the mode darkening and the drums thickening as the stack
  climbs. Every piece rolls its own key, tempo, time signature (4/4, and
  sometimes 3/4 or 6/8) and drum kit, ends with a final chorus a whole tone
  up, and comes home through an outro so it loops
• Where a beat is the point, a piece can roll a hard-bass groove instead: a
  saturated sub kick on every beat with the whole mix ducking out of its way,
  the bass answering on the offbeats under a sawtooth donk, chord stabs
  between them, and release-cut piano scattered over the sixteenths. Those
  pieces usually take the IVM7-III7-vi-I7 changes J-pop calls the maru-sa
  progression, whose two secondary dominants are the only chords here that
  borrow from outside the key
• MUSIC room: pick a seed, a preset and a groove and listen, with the piano
  roll filling the screen. Set BEVYTRIS_MUSIC_SEED to replay a session note
  for note
• SFX from CC0 samples plus procedurally synthesized bells and booms
