Crimson Pulse

Every texture is authored at the *exact* native pixel geometry of the vanilla
26.3 client, so the pack scales cleanly at every GUI scale setting with zero
layout drift. No `.mcmeta` sidecars are shipped - all nine-slice and animation
rules fall back to the vanilla defaults.

## What it changes

| Area | Result |
| --- | --- |
| Container screens | True-black recessed panels with a **dark brushed-steel** surface, crimson corner brackets, a hairline crimson rail, ruler ticks and ember flow chevrons - covering the survival inventory, chests (`generic_54`), crafting table, furnace / smoker / blast furnace, enchanting table, anvil, smithing, brewing stand, hopper, dispenser, shulker box, loom, cartography table, stonecutter, crafter, beacon, horse, villager, gamemode switcher and the three creative item tabs |
| HUD | Hearts rebuilt as **pulsating crimson energy cells** (bright core, red-to-oxblood gradient, glowing container rim), steel armour cells, ember nutrient capsules, pale-blue air bubbles, plus a brushed-steel hotbar, crimson selection frame, off-hand slots, XP / jump bars, boss bars and the locator bar |
| Crosshair | A precision reticle: bright centre dot, four cardinal ticks and a dashed outer pulse ring, with a matching crimson -> ember attack-cooldown ring and hotbar bar that expands as the cooldown fills |
| Title screen | The vanilla panorama is replaced by six procedural 1024x1024 crimson-void faces - a radial core glow, a star field and range rings - so the main menu reads as true-black dark mode instead of a bright landscape |
| Advancement screen | A dark steel window frame with crimson rails, twelve tab frames, five tab badges and the obtained / unobtained title and icon frames |
| Books & signs | The written book page, the thirteen sign boards and the thirteen hanging signs are re-drawn as steel plates with crimson edging |
| Menus & widgets | True-black menu backdrops, dark-mode buttons, sliders, text fields, checkboxes, tabs, scrollbars, lock buttons, tooltips, popups and a full set of menu icons |
| Typography | The re-authored 5x7 pixel alphabet is **inked bold** - every stroke is thickened one pixel to the right - so data readouts and error logs hit harder while keeping the vanilla 8x8 cell grid |
| Pack icon | `pack.png`, a brushed-steel plate with a crimson pulse reticle and heartbeat trace |
