Adds generic *.flat.css bundles for every tier, replacing the single bricks-branded flat bundle.

Bundles produced in dist/

Layered	Flat sibling
slashed.essential.css	slashed.essential.flat.css
slashed.optimal.css	slashed.optimal.flat.css
slashed.optimal-components.css	slashed.optimal-components.flat.css
slashed.optimal-utilities.css	slashed.optimal-utilities.flat.css
slashed.full.css	slashed.full.flat.css

Each ships with .min.css + .min.css.map. Same minifier config (lightningcss, no down-levelling).

Consumer-facing API

// Layered (cascade-managed) — unchanged
import 'slashed';                       // = slashed/full
import 'slashed/essential';
import 'slashed/optimal';
// …

// Flat (unlayered) — new
import 'slashed/flat';                  // = slashed/full/flat (convenience alias)
import 'slashed/essential/flat';
import 'slashed/optimal/flat';          // same file set as the old slashed/bricks
import 'slashed/optimal-components/flat';
import 'slashed/optimal-utilities/flat';
import 'slashed/full/flat';

What changed

• bundle.config.json — five new flat: true entries; bricks entry removed.
• package.json — ./bricks export removed; new ./flat and ./<tier>/flat exports added.
• scripts/bundle.js — comment in stripLayerWrappers genericised (no longer references Bricks Builder by name).
• dist/ — stale slashed.bricks.* files removed; new *.flat.{css,min.css,min.css.map} siblings emitted.
• package-lock.json — incidental: lockfile version field synced to 0.2.10 (was drifting at 0.2.5).

Tested

• node scripts/bundle.js produces all 10 layered + flat bundles cleanly.
• Spot-check: slashed.full.flat.css has 0 top-level @layer declarations vs 17 in slashed.full.css — strip works as intended.
• Pre-commit hook ran (lint + rebuild + restage) on commit.

Versioning

Lands as 0.2.11 under .release-it.json's hardcoded "increment": "patch" + "ignoreRecommendedBump": true. Replaces #60.

Summary by CodeRabbit

• New Features

  • Added flat CSS bundle variants for all optimization levels (essential, optimal, optimal-components, optimal-utilities, full) available via new import subpaths.

• Chores

  • Removed ./bricks export subpath.
  • Updated internal documentation.

📝 Walkthrough

Walkthrough

The PR extends the bundle system with flattened CSS variants. Five new flat bundle configurations are added to bundle.config.json for essential, optimal, optimal-components, optimal-utilities, and full tiers, each with flat: true and corresponding CSS input file lists. Public subpath exports in package.json are updated to expose these new flat builds (and remove the .bricks export), allowing users to import pre-flattened CSS alongside existing layered outputs.

Changes

Flat Bundle Outputs and Public Exports

Layer / File(s)	Summary
Flat bundle configuration definitions bundle.config.json	Five new bundle entries with flat: true are defined for essential, optimal, optimal-components, optimal-utilities, and full tiers, each enumerating corresponding CSS inputs and producing separate flattened outputs (dist/slashed.*.flat.css).
Package exports for flat CSS variants package.json	Exports map is updated with six new subpath entries (./essential/flat, ./optimal/flat, ./optimal-components/flat, ./optimal-utilities/flat, ./full/flat, ./flat), all pointing to their respective flat CSS outputs; the ./bricks export is removed.

Preserve ./bricks as a compatibility export (or ship an intentional major breaking change).

Dropping the ./bricks subpath from package.json will break existing consumers importing slashed/bricks at resolution time. Add a deprecated alias pointing to the existing ./optimal/flat bundle (./dist/slashed.optimal.flat.css).

Suggested compatibility patch

     "./full/flat": "./dist/slashed.full.flat.css",
