v1.3.0

Added

• Shadow color, transition, and pride MiniMessage tags (chat.colored-gated, shadow color also has a MineDown shortcut: [Text](shadow:#hex)).
• Keybind, insertion, font, translatable (lang/lang_or), player head, and sprite MiniMessage tags, gated behind a new chat.cosmetic permission. Note: <head>/<sprite> require Paper 1.21.10+ (Adventure 4.25.0) — on older servers the tag is silently unrecognized regardless of permission.
• Entity selector, scoreboard, and NBT MiniMessage tags, gated behind a new chat.advanced permission (OP-only by default — these can expose live server state). Resolved against the message sender via Paper's PaperComponents.resolveWithContext (needs Paper 1.21.4+; older servers fall back to showing the raw pattern, e.g. @e[limit=5], instead of resolved names).
• debug config option — logs the fully processed message string plus the raw component JSON for every chat message. Off by default, noisy; only meant for troubleshooting.
• console_format_colors config option — renders console/log output with real ANSI colors (via Paper's ComponentLogger) instead of plain text.

Fixed

• Players without chat.colored could bypass the color restriction entirely by typing raw MiniMessage tags (<red>, <gradient:...>, etc.) directly instead of MineDown syntax — only legacy &/hex codes were being stripped. Now the whole color-tag family is stripped consistently, MineDown args and raw tags alike.
• <gradient:#hex:#hex>, <transition:#hex:#hex>, and <shadow:#hex> (raw-typed, MineDown-generated, or baked into channels.yml) were silently broken — hex-to-MiniMessage conversion ran indiscriminately over the whole string and rewrote hex color arguments into nested <#hex> tags, which MiniMessage can't parse as a color, so the tag fell back to literal text. Hex conversion now skips content already inside a tag.
• <!shadow> (the disable-shadow alias) wasn't covered by the chat.colored gate — the regex only accounted for </tag> closing syntax, not <!tag>.
• <selector>/<score>/<nbt> reached the client unresolved (showing the raw pattern, e.g. @e[limit=5], instead of resolved names) because nothing ever supplied Paper the sender context these components need to render server-side — see Added above.
• Console log only ever stripped legacy & codes, leaving raw MiniMessage tags (<selector:...>, <yellow>, etc.) visible as literal text; now properly deserialized and rendered as plain text (or ANSI colors with console_format_colors), with hover/click content naturally excluded either way.
• GitLab releases shipped with no real patch notes (just a bare "SlateChat x.y.z" description) — the CI pipeline now pulls the matching version section from this changelog instead.

Changed

• Docs reorganized by audience: docs/formatting.md now covers only everyday chat syntax, docs/formatting-advanced.md covers admin/config-only tags, and docs/permissions.md is now the single canonical permission table (previously duplicated across the README and two other docs).
